Hubble finds a black hole igniting star formation in a dwarf galaxy
Black holes are often described as the monsters of the universe—tearing apart stars, consuming anything that comes too close, and holding light captive. Detailed evidence from the NASA/ESA Hubble Space Telescope, however, shows a black hole in a new light: fostering, rather than suppressing, star formation. Hubble imaging and spectroscopy of the dwarf starburst galaxy Henize 2-10 clearly show a gas outflow stretching from the black hole to a bright star birth region like an umbilical cord, triggering the already dense cloud into forming clusters of stars. Astronomers have previously debated that a dwarf galaxy could have a black hole analogous to the supermassive black holes in larger galaxies. Further study of dwarf galaxies, which have remained small over cosmic time, may shed light on the question of how the first seeds of supermassive black holes formed and evolved over the history of the universe.
This dwarf starburst galaxy Henize 2-10 sparkles with young stars in this Hubble visible-light image. The bright region at the center, surrounded by pink clouds and dark dust lanes, indicates the location of the galaxy's massive black hole and active stellar nurseries.

One of a pair
In this image the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, more than 50 million light-years from Earth. This galaxy is one of a pair, but NGC 1317’s rowdy larger neighbour NGC 1316 lies outside Hubble’s field of view. Despite the absence here of its neighbouring galaxy, NGC 1317 is accompanied in this image by two objects from very different parts of the Universe. The bright point ringed with a criss-cross pattern is a star from our own galaxy surrounded by diffraction spikes, whereas the redder elongated smudge is a distant galaxy lying far beyond NGC 1317. The data presented in this image are from a vast observing campaign of hundreds of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Combined with data from the ALMA array in the Atacama desert, these observations help astronomers chart the connections between vast clouds of cold gas and the fiercely hot young stars that form within them. ALMA’s unparalleled sensitivity at long wavelengths identified vast reservoirs of cold gas throughout the local Universe, and Hubble’s sharp vision pinpointed clusters of young stars, as well as measuring their ages and masses. Often the most exciting astronomical discoveries require this kind of telescope teamwork, with cutting-edge facilities working together and providing astronomers with information across the electromagnetic spectrum. The same applies to future telescopes, with Hubble’s observations laying the groundwork for future science with the NASA/ESA/CSA James Webb Space Telescope.

Cosmological curiosity
This image from the NASA/ESA Hubble Space Telescope features the spiral galaxy Mrk 1337, which is roughly 120 million light-years away from Earth in the constellation Virgo. Hubble’s Wide Field Camera 3 snapped Mrk 1337 at a wide range of ultraviolet, visible and infrared wavelengths, producing this richly detailed image. Mrk 1337 is a weakly barred spiral galaxy, which as the name suggests means that the spiral arms radiate from a central bar of gas and stars. Bars occur in roughly half of spiral galaxies, including our own galaxy the Milky Way.
These observations are part of a campaign to improve our knowledge of how fast the universe is expanding. They were proposed by Adam Riess, who was awarded a Nobel Laureate in physics 2011 for his contributions to the discovery of the accelerating expansion of the Universe, alongside Saul Perlmutter and Brian Schmidt.

Crew-3 rehearse for launch
ESA astronaut Matthias Maurer and NASA astronauts Raja Chari, Tom Marshburn and Kayla Barron move through the steps for their upcoming launch during a dry dress rehearsal at NASA’s Kennedy Space Center in Florida, USA.
As members of Crew-3, they will be launched to the International Space Station on SpaceX’s Crew Dragon spacecraft “Endurance”. The first launch attempt is scheduled for 07:21 CET (06:21 GMT, 02:21 EDT) Sunday 31 October 2021, with a backup date of 3 November.
This will be the first spaceflight for Matthias who has selected the name “Cosmic Kiss” for his six months in orbit. During the flight to and from space, he and Kayla will be what is known as “mission specialists”. They will work with commander Raja Chari and pilot Tom Marshburn to monitor the spacecraft during the dynamic launch and re-entry phases of flight.
On Station, Matthias will become a long-duration crew member, spending around six months living and working in orbit. During this time, he will support more than 35 European experiments and numerous international experiments on board.
Matthias is the second European to fly on a SpaceX Crew Dragon. The first was ESA astronaut Thomas Pesquet who flew as part of Crew-2.

Crew-3 say cheese
ESA astronaut Matthias Maurer and his NASA crew mates Raja Chari, Thomas Marshburn and Kayla Barron are all smiles as they arrive at NASA’s Kennedy Space Center in Florida, USA on 26 October 2021.
Collectively, the astronauts make up Crew-3 and will travel to the International Space Station on the SpaceX Crew Dragon spacecraft “Endurance”. The first launch opportunity for Crew-3 is 07:21 CET (06:21 GMT, 02:21 EDT) Sunday 31 October 2021, with a backup date of 3 November.
The Dragon will dock with the Space Station 22 hours after launch, allowing for a short overlap with the Crew-2 members who are due to depart the Station in the coming week.
With both Matthias and ESA astronaut and current Space Station Commander Thomas Pesquet on board, Europe will have two astronauts resident in space – a rare occurrence.
The name of Matthias’s mission is “Cosmic Kiss”. This is Matthias’s first mission, and he will be the 600th human to fly to space.
Once in orbit, Matthias will spend around six months living and working in microgravity as he supports more than 35 European experiments and numerous international experiments on board.
Matthias is also certified to perform Extra Vehicular Activity (EVA) in both the Russian Orlan and American EMU spacesuits. He is expected to perform a Russian spacewalk during his mission as part of initial operations for the European Robotic Arm (ERA) that was launched to the Station in July 2021.

Four filter fusion
This stellar whirlpool is a spiral galaxy named NCG 7329, which has been imaged by Hubble’s Wide Field Camera 3 (WFC3). Creating a colourful image such as this one using a telescope such as Hubble is not as straightforward as pointing and clicking a camera. Commercial cameras will typically try to collect as much light of all visible wavelengths as they can, in order to create the most vibrant images possible. In contrast, raw images collected by Hubble are always monochromatic, because astronomers typically want to capture very specific ranges of wavelengths of light at any time, in order to do the best, most accurate science possible. In order to control which wavelengths of light will be collected, Hubble’s cameras are equipped with a wide variety of filters, which only allow certain wavelengths of light to reach the cameras’ CCDs (a CCD is a camera’s light sensor — phone cameras also have CCDs!).
How are the colourful Hubble images possible given that the raw Hubble images are monochromatic? This is accomplished by combining multiple different observations of the same object, obtained using different filters. This image, for example, was processed from Hubble observations made using four different filters, each of which spans a different region of the light spectrum, from the ultraviolet to optical and infrared. Specialised image processors and artists can make informed judgements about which optical colours best correspond to each filter used. They can then colour the images taken using that filter accordingly. Finally, the images taken with different filters are stacked together, and voila! The colourful image of a distant galaxy is complete, with colours as representative of reality as possible.

Hubble experiences déjà vu
This jewel-bright Picture of the Week features the spiral galaxy NGC 2903. This image was captured using Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3), which were installed on Hubble in 2002 and 2009 respectively. Interestingly, Hubble has observed this particular galaxy before, in 2001, when neither the ACS or the WFC3 had yet been installed. The 2021 image boasts higher resolution, which means that NGC 2903 is more finely detailed than in the 2001 image. The ACS and WFC2 collectively cover a wide range of ultraviolet, optical and infrared wavelengths, which means that the 2021 image also has superior wavelength coverage to that of its 20-year-old predecessor. The 2001 image was taken using the Wide Field Planetary Camera 2 (WFPC2), which was Hubble’s workhorse instrument from 1993 until 2009 when it was replaced by the WFC3.
Hubble has a long and fascinating history of crewed service missions, which were performed in order to correct for imperfections in Hubble’s mirror, to update Hubble’s technical systems, and to remove old instruments and install new ones. One of Hubble’s most remarkable features is it’s incredible longevity, and this would not have been possible with the great success of the servicing missions. The juxtaposition of the 2001 and 2021 images of NGC 2903 — both remarkable images for their time — highlights the value of a stable, accessible platform in space that can reliably collect data, not only year after year, but decade after decade.

Hubble celebrates Halloween with a glowering carbon star
The NASA/ESA Hubble Space Telescope celebrates Halloween this year with a striking observation of the carbon star CW Leonis, which resembles a baleful orange eye glaring from behind a shroud of smoke.
CW Leonis glowers from deep within a thick shroud of dust in this image from the NASA/ESA Hubble Space Telescope. Lying roughly 400 light-years from Earth in the constellation Leo, CW LEonis is a carbon star — a luminous type of red giant star with a carbon-rich atmosphere. The dense clouds of sooty gas and dust engulfing this dying star were created as the outer layers of CW Leonis itself were thrown out into the void.
When small to intermediate-mass stars run out of hydrogen fuel in their cores, the outwards pressure that balances the crush of gravity within their cores falls out of equilibrium, causing the star to start collapsing. As the core collapses, the shell of plasma surrounding the core becomes hot enough to begin fusing hydrogen, generating enough heat to dramatically expand the outer layers of the star and turn it into a bloated red giant. Stars in that phase of life eject huge amounts of gas and dust outwards into space, eventually jettisoning their outer layers. In the case of the carbon star CW Leonis, this process has surrounded the star with a dense pall of sooty dust.
Along with CW Leonis’s smoky veil, the vibrant orange and green tints of this image make it a fitting celebration of Halloween. Hubble has captured a ghoulish gallery of halloween images over the years — from ghostly faces and cosmic bats to a carved pumpkin formed from binary stars. This year’s image resembles a single, baleful eye of cosmic proportions glaring out from within a cloud of smoke.
While these observations make for a striking image, they were originally made to answer pressing scientific questions about CW Leonis. As the closest carbon star to Earth, CW Leonis gives astronomers the chance to understand the interaction between the star and its surrounding envelo

Crater landslide Mars
Crater landslide.
A 5 km-long landslide dominates this scene, captured by the ExoMars Trace Gas Orbiter on 13 April 2021. The landslide has occurred at the rim of a 35 km wide crater in the Aeolis region of Mars (151.88¡E/27.38¡S).
Landslides are geomorphological processes occurring under specific environmental conditions. On Mars as on Earth, they come in various shapes and sizes, and Earth analogues are used to understand similar processes seen on planetary bodies.
For this particular landslide the failure area, from where the material collapsed, is slightly out of frame, although the transport and deposit zones show great details such as longitudinal striations and flow ridges. The impact craters on the lobe indicates that this is not a recent event, but it remains a challenge to accurately date its formation.
TGO arrived at Mars in 2016 and began its full science mission in 2018. The spacecraft is not only returning spectacular images, but also providing the best ever inventory of the planetÕs atmospheric gases, and mapping the planetÕs surface for water-rich locations. It will also provide data relay services for the second ExoMars mission comprising the Rosalind Franklin rover and Kazachok platform, when it arrives on Mars in 2023. Credit: ESA / eyevine

Drilling on Mars-like terrain
Drilling on Mars-like terrain. ESAÕs Rosalind Franklin twin rover on Earth has drilled down and extracted samples 1.7 metres into the ground Ð much deeper than any other martian rover has ever attempted.
The first samples have been collected as part of a series of tests at the Mars Terrain Simulator at the ALTEC premises in Turin, Italy. The replica, also known as the Ground Test Model, is fully representative of the rover set to land on Mars.
The Rosalind Franklin rover is designed to drill deep enough, up to two metres, to get access to well-preserved organic material from four billion years ago, when conditions on the surface of Mars were more like those on infant Earth.
Rosalind FranklinÕs twin has been drilling into a well filled with a variety of rocks and soil layers.
The drill was developed by Leonardo, while Thales Alenia Space is the prime contractor for ExoMars 2022. The ExoMars programme is a joint endeavour between ESA and Roscosmos.

Orphan cloud discovered in galaxy cluster
Orphan cloud discovered in galaxy cluster.
New observations made with ESAÕs X-ray XMM Newton telescope have revealed an Òorphan cloudÓ Ð an isolated cloud in a galaxy cluster that is the first discovery of its kind.
A lot goes on in a galaxy cluster. There can be anything from tens to thousands of galaxies bound together by gravity. The galaxies themselves have a range of different properties, but typically contain systems with stars and planets, along with the material in between the stars Ð the interstellar medium. In between the galaxies is more material Ð tenuous hot gas known as the intercluster medium. And sometimes in all the chaos, some of the interstellar medium can get ripped out of a galaxy and get stranded in an isolated region of the cluster, as this new study reveals.
Unexpected discovery
Abell 1367, also known as the Leo Cluster, is a young cluster that contains around 70 galaxies and is located around 300 million light-years from Earth. In 2017, a small warm gas cloud of unknown origin was discovered in A1367 by the Subaru telescope in Japan. A follow-up X-ray survey to study other aspects of A1367 unexpectedly discovered X-rays emanating from this cloud, revealing that the cloud is actually bigger than the Milky Way.
This is the first time an intercluster clump has been observed in both X-rays and the light that comes from the warm gas. Since the orphan cloud is isolated and not associated with any galaxy, it has likely been floating in the space between galaxies for a long time, making its mere survival surprising.
The discovery of this orphan cloud was made by Chong Ge at the University of Alabama in Huntsville, and colleagues, and the study has been published in Monthly Notices of the Royal Astronomical Society.
Along with data from XMM-Newton and Subaru, Chong and colleagues also used the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to observe the cluster in visible light.

Cygnus NG-15 cargo vehicle
On its way...
ESA astronaut Thomas Pesquet snapped this image of the Cygnus NG-15 cargo vehicle over Earth during his second long-duration mission known as Alpha. He posted it on social media saying: "So long Cygnus! Thanks for all the supplies you brought up here and thanks for clearing out the trash as you leave. Cygnus NG-15 arrived at the Station long before me on 22 February and has served as an extra module since then. Yesterday we said goodbye but packed it with waste first that will burn up on reentry, clearing some space inside the Space Station. The distinctive solar panels you might have seen in many previous images, they are now gone."
Thomas was launched to the International Space Station for his second mission, Alpha, on 23 April 2021. He will spend six months living and working on the orbital outpost where he will support more than 200 international experiments in space.Credit: ESA / eyevine

A Scattering of Stars
This Picture of the Week depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic Cloud. The cluster Ñ which is in the constellation Tucana (The Toucan) Ñ contains a multitude of stars, many of which are scattered across this striking image. Pictures of the Week from the NASA/ESA Hubble Space Telescope show us something new about the Universe. This image, however, also contains clues about the inner workings of Hubble itself. The criss-cross patterns surrounding the stars in this image Ñ known as diffraction spikes ÑÊ were created when starlight interacted with the four thin vanes supporting HubbleÕs secondary mirror. As star clusters form from a single primordial cloud of gas and dust, all the stars they contain are roughly the same age. This makes them useful natural laboratories for astronomers to learn how stars form and evolve. This image uses observations from HubbleÕs Wide Field Camera 3, and incorporates data from two very different astronomical investigations. The first aimed to understand why stars in star clusters appear to evolve differently from stars elsewhere, a peculiarity first observed by the Hubble Space Telescope. The second aimed to determine how large stars can be before they become doomed to end their lives in cataclysmic supernova explosions. Links Video of A Scattering of Stars Credit: ESA / eyevine

Retro meets retrofit
Retro meets retrofit.
Retro meets retrofit: The Novespace Air Zero G aircraft is seen here next to Douglas the 1962 VW Transporter. The two are in Paderborn, Germany for the 76th ESA Parabolic Flight Campaign.
The refitted A310 Air Zero G aircraft flies in parabolas that offer teams from various research institutes and universities altered states of gravity to perform experiments and technology demonstrations. Experiments span many disciplines including complex fluidics and human physiology, and this campaign is no exception.
Running from 25 June to 1 July, the 76th campaign features an experiment studying the effect of gravity on hydrodynamics to better protect spacecraft and science instruments from the temperature fluctuations in space; a study on how immune cells flow under the stress of spaceflight; an experiment studying spinal stiffness under microgravity to mitigate lumbar pain for both astronauts and patients on Earth, to name a few.
A typical parabolic flight campaign involves three flights and requires a week of on-site preparation. Each flight offers 31 periods of weightlessness. The aircraft can also fly in arcs that provide lunar or martian gravity levels by adjusting the angle of attack of the wings. Each flight of this particular campaign will split the gravity states, flying one third of parabolas at martian-G, one third at lunar-G, and one third at zero-G.
The aircraft flies close to maximum speed and pulls the nose up to a 45¡ angle, then cuts the power to fall over the top of the curve. Whilst falling freely the passengers and experiments experience around 20 seconds of microgravity, until the plane is angled 45¡ nose-down, before pulling out of the dive to level off with normal flight.
These Òpull upÓ and Òpull outÓ manoeuvres before and after the weightless period increase gravity inside the plane up to 2g, but that is just Credit: ESA / eyevine

New solar arrays for the International Space Station
New solar arrays for the International Space Station.
New solar arrays before installation on the farthest port side of the International Space Station as seen by HD cameras outside the orbital complex. These arrays, called iROSA for ISS Roll-Out Solar Array, are rolled up into tubes for transport.
These panels are smaller but more efficient than the existing solar arrays, which are showing signs of degradation after years of continuous work in outer space. The combination of the old and new arrays will increase the power generation to a total of 215 kilowatts.
ESA astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough performed three spacewalks in the span of 10 days to install new solar arrays that will generate between 20 and 30% more electricity on the International Space Station.
The duo took them from their storage area outside the Space Station to the worksite. There the spacewalkers secured the rolled arrays for them to be unfolded, connected and finally unfurled over the existing arrays.Credit: ESA / eyevine
