This image features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth, that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters do: where galaxy clusters can contain hundreds or even thousands of constituent galaxies, galaxy groups do not typically include more than 50. The Milky Way is actually part of a galaxy group, known as the Local Group, which contains two other large galaxies (Andromeda and the Triangulum galaxy), as well as several dozen satellite and dwarf galaxies. The NGC 3783 galaxy group, meanwhile, contains 47 galaxies. It also seems to be at a fairly early stage of its evolution, making it an interesting object of study.
Whilst the focus of this image is the spiral galaxy NGC 3783, the eye is equally drawn to the very bright object in the lower right part of this image. This is the star HD 101274. The perspective in this image makes the star and the galaxy look like close companions, but this is an illusion. HD 101274 lies only about 1530 light-years from Earth, meaning it is about 85 thousand times closer than NGC 3783. This explains how a single star can appear to outshine an entire galaxy!
NGC 3783 is a type-1 Seyfert galaxy, which is a galaxy with a bright central region — so it’s particularly bright itself, as far as galaxies go. In this image it is recorded by Hubble in incredible detail, from its glowing central bar to its narrow, winding arms and the dust threaded through them, thanks to five separate images taken in different wavelengths of light. In fact, the galactic centre is bright enough to Hubble that it exhibits diffraction spikes, normally only seen on stars such as HD 101274.
[Image Description: A spiral galaxy, seen face-on to the viewer. The bright centre of the galaxy is crossed by a glowing bar, and it is surrounded by tightly-wound spiral arms, forming a circular shape with relatively clear edges. Faraway galaxies can be seen around it, along with a few bright stars, on a dark background. One star to the right of the galaxy is very large and extremely bright with long diffraction spikes around it.]

Early on 8 April 2024, a citizen scientist found a comet in images from the ESA/NASA Solar and Heliospheric Observatory (SOHO). It follows the recent discovery of SOHO’s 5000th comet. But this one – named Comet SOHO-5008 – was special for a different reason.
Karl Battams (US Naval Research Lab), manager of the SOHO Sungrazer Project, predicted that comet SOHO-5008 would be visible during the total solar eclipse, which was due to plunge parts of the United States and Mexico into darkness later that very same day.
Petr Horálek, from the Institute of Physics in Opava (Czechia), was in Mexico for the eclipse. The clouds cleared and Petr could take this beautiful shot of the Sun’s awe-inspiring corona. To the lower left of the Sun, Comet SOHO-5008 is revealed.
Soon after Petr captured the comet on camera, it met its demise, coming so close to the Sun that it disintegrated.
Observations of these ‘sungrazing’ comets from the ground are extremely rare, and this sighting was only possible thanks to the total solar eclipse.
The image is a composite of 100 frames, with the wide corona imaged at a focal length of 200 mm (exposure time from 1/4000 to 2 seconds) and the inner corona imaged at a focal length of 1100 mm (exposure time from 1/500 to 4 seconds).
SOHO’s prowess as a comet-hunter was unplanned, but turned out to be an unexpected success. With its clear view of the Sun’s surroundings, SOHO can easily spot sungrazing comets. This has made it the most prolific discoverer of comets in astronomical history.

SOHO is a cooperative effort between ESA and NASA. Mission control is based at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. SOHO’s Large Angle and Spectrometric Coronagraph Experiment (LASCO), the instrument that provides most of the comet imagery, was built by an international consortium, led by the US Naval Research Lab.

ESA’s new generation of astronauts had a taste of space on the special Airbus ‘Zero G’ A310 aircraft earlier this week. The rookies were supported by experienced European astronauts and instructors during several parabolic flights in Bordeaux, France.
Parabolic flight campaigns recreate the 'weightless’ conditions similar to those experienced in space, and are often used to run science experiments, validate space instruments and train astronauts before spaceflight.
ESA's latest astronaut recruits flew through repeated parabolas that gave them brief bursts of microgravity. They flew through 30 parabolas per flight, with up to 22 seconds of microgravity at a time. In total, the passengers experienced around 10 minutes of weightlessness inside the aircraft at the top of each parabolic manoeuvre.
Standing by the plane, from left to right, are astronaut candidates Pablo Álvarez Fernández, Rosemary Coogan, Sophie Adenot, Raphaël Liégeois and Marco Sieber.
Project astronaut Slawosz Uznanski, member of the astronaut reserve John McFall and Australian Space Agency candidate Katherine Bennell-Pegg also joined the ride in preparation for future spaceflight opportunities.
The campaign offered the astronaut candidates a glimpse of their future working conditions. A first flight helped them familiarise their bodies with the challenges of inertia and orientation in weightlessness. While movements do not require any effort, stopping and controlling one's motion need practice.
During the second flight the crew took turns on several training worksites to handle tools, such as screwdrivers, and moved along the cabin using tethers, handrails and spacesuit gloves. One of the exercises saw them performing cardiopulmonary resuscitation techniques on others, better known as CPR.
Experienced spacewalkers were by their side. ESA astronauts Alexander Gerst and Matthias Maurer shared their knowledge acting as safety and support operators during the flights.
Another veteran spacewalker was at the cockpit of the aircraft. ESA astronaut and pilot Thomas Pesquet placed the ‘Zero G’ plane on a parabolic flight path by pulling up the aircraft sharply and reducing the thrust repeatedly.
“If that’s not the perfect preparation for a flight to the International Space Station, I don’t know what is! All of them are naturals and just straight out enjoyed this first taste of what’s to come,” said Thomas on social media.
The three-day campaign wrapped up a year-long basic training for the astronaut candidates. The astronaut candidates from ESA and the Australian Space Agency will soon become fully qualified astronauts eligible for space missions.
Watch the graduation ceremony live on ESA Web TV 2 and ESA YouTube on Monday, 22 April, at 9:00 BST (10:00 CEST) from ESA’s European Astronaut Centre in Cologne, Germany.

This NASA/ESA Hubble Space Telescope image of the barred spiral galaxy UGC 12158 looks like someone took a white marking pen to it. In reality it is a combination of time exposures of a foreground asteroid moving through Hubble’s field of view, photobombing the observation of the galaxy. Several exposures of the galaxy were taken, which is evidenced by the dashed pattern.
The asteroid appears as a curved trail as a result of parallax: Hubble is not stationary, but orbiting Earth, and this gives the illusion that the faint asteroid is swimming along a curved trajectory. The uncharted asteroid is inside the asteroid belt in our Solar System, and hence is 10 trillion times closer to Hubble than the background galaxy.
Rather than being a nuisance, this type of data is useful to astronomers for doing a census of the asteroid population in our Solar System.
[Image description: This is a Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape made up of bright blue stars wound around a yellow-white hub of central stars. The hub has a slash of stars across it, called a bar. The galaxy is tilted face-on to our view from Earth. A slightly S-shaped white line across the top is the Hubble image of an asteroid streaking across Hubble’s view. It looks dashed because the image is a combination of several exposures of the asteroid flying by like a race car.]
