Galactic shock is changing Stephan’s Quintet in enigmatic ways, according to ALMA and JWST.

New observations made with the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) allowed researchers to see the complex interactions within the multi-galaxy collision event known as Stephan’s Quintet.

Stephan’s Quintet is a group of five galaxies-NGC 7,317, NGC 7318a, NGC 7318b, NGC 7,319, and NGC 7,320, located about 270 million light-years from Earth in the constellation Pegasus.

A research team using new methods to analyze data from NASA’s Curiosity, a rover operating on Mars since 2012, was able to independently verify that fracture halos contained opal, on Earth a gemstone formed by the alteration of silica by water.

The study finds that the vast subsurface fracture networks would have provided conditions that were potentially more habitable than those on the surface.

In 2012, NASA sent the Curiosity rover to Mars to explore Gale Crater, a large impact basin with a massive, layered mountain in the middle. As Curiosity has traversed along the Mars surface, researchers have discovered light-toned rocks surrounding fractures that criss-cross certain parts of the Martian landscape, sometimes extending out far into the horizon of rover imagery. Recent work finds that these widespread halo networks served as one of the last, if not the last, water-rich environments in a modern era of Gale Crater. This water-rich environment in the subsurface would have also provided more habitable conditions when conditions on the surface were likely much more harsh.

When the Fermi Gamma-Ray Space Telescope entered low-Earth orbit in 2008, it opened our eyes to a whole new Universe of high-energy radiation.

One of its more curious discoveries was the Fermi Bubbles: giant, symmetrical blobs extending above and below the galactic plane, 25,000 light-years on each side from the Milky Way’s center, glowing in gamma-ray light – the highest energy wavelength ranges on the electromagnetic spectrum.

Then, in 2020, an X-ray telescope named eROSITA found another surprise: even bigger bubbles extending over 45,000 light-years on each side of the galactic plane, this time emitting less energetic X-rays.

A study of intracluster light (ICL) in ten high-redshift galaxy clusters finds evidence that gradual stripping may not be the dominant mechanism of ICL formation, but may occur alongside the formation and growth of the brightest cluster galaxies, and/or accretion of preprocessed stars.

The first orbital space launch from British soil is scheduled to take off on Monday.

A modified Boeing 747 airplane known as Cosmic Girl will take off from Spaceport Cornwall in England. Once it reaches 35,000 feet in the air, the converted aircraft will deploy a rocket, called LauncherOne, into space.

The LauncherOne rocket will deliver several payloads into orbit, including Wales’ first satellite and the first ever satellite launched by Oman to observe Earth.

A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said.

The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year.

After traveling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.
