"Using the set of first-light observations from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph, a team of more than 50 astronomers, led by Dr. Marina Arnaudova at the University of Hertfordshire, has presented the first WEAVE scientific results on Stephan's Quintet in the Monthly Notices of the Royal Astronomical Society."

Satellite space junk might wreak havoc on the stratosphere
Hundreds of defunct satellites plunge toward Earth every year. Scientists are studying how the chemical stew left in their wake impacts the atmosphere.Carolyn Gramling (Science News)
Due to a rare, lucky cosmic alignment, the combined gravity of two galaxies bent light like spaghetti & split a distant quasar into six different images.
This six-part image could allow a very accurate measure of the expansion of the universe.

Westerlund 2 is a giant cluster of about 3,000 stars located 20,000 light-years away from Earth in the constellation Carina. These stars sculpt the surrounding nebula, carving out a cavity lined with a fantasy landscape of pillars, ridges, and valleys. The pillars, composed of dense gas and dust, are incubators for new stars. They are a few light-years tall and point to the central star cluster.

A neutron star is like a huge atomic nucleus held together by gravity rather than the strong nuclear force. But we don’t fully understand how neutrons interact at extreme temperatures and densities.Jatan Mehta (Jatan’s Space)

It originated with Swedish philosopher Emanuel Swedenborg, way back in 1734. But only now can astronomers directly observe that, yes, planets really do form in clouds around newborn stars. Science takes time.

Cosmogenesis (8) : The Nebular Hypothesis, by Jean-Pierre Luminet
Sequel of the preceding post Cosmogenesis (7) : The Date of the Creation The Nebular Hypothesis The ancient Babylonians had a different idea of how the world began. They believed that it had evolved rather than being created instantaneously.Jean-Pierre LUMINET (e-LUMINESCIENCES: the blog of Jean-Pierre Luminet)
Each of the arrow-marked blobs is a likely planet-in-the-making around the infant star FU Orionis (great name), located 1,350 light years away in the constellation Orion.

Direct imaging of exoplanets
Over the past 4 decades, the exploration of planets beyond our solar system has yielded the discovery of over 5600 exoplanets orbiting different stars.arXiv.org
Savage noted the engineering differences between the two. The Apollo suit was a bit complicated, requiring separate pieces of the suit to be put together before a backpack could be attached. The Krechet had a one-piece hardbody interior that could only be entered via backpack, a design that NASA is currently using in their Artemis space suits.

Sputnik 04.10.1957 The First Artificial Earth Satellite.
Spacecraft PS-1 (the simplest satellite-1) was a ball with a diameter of 58 centimeters, weighed 83.6 kilograms, was equipped with four pin antennas with lengths of 2.4 and 2.9 meters to transmit signals from battery-powered transmitters.

How I Killed Pluto and Why It Had It Coming, by Mike Brown
If you are in my generation, Pluto losing its spot as a planet is likely a sore topic for you. I was therefore delighted to find this book, and learn more about just what the heck happened and why. By the end of the book I was not only stunned by the amount of work that went into the process, but I also learned to understand why Pluto is not a planet anymore.

Life seems to have been found. But not where they were looking
It is unlikely that it will be possible to explore even the nearest exoplanets with the help of automatic spacecraft in the current century. It is quite possible, however, that the answer will be found very close, on our closest neighbor in the solar system - on Venus. The surface temperature of the planet (735 K, or 462°C) and the enormous pressure (87–90 atm) of its gas envelope with a density of 65 kg/m3, consisting mainly of carbon dioxide (96.5%), nitrogen (3.5%), and traces of oxygen (less than 2·10–5%), are close to the physical conditions on many exoplanets of a special class.
Recently, television images (panoramas) of the surface of Venus, obtained thirty years ago or more, have been re-examined and processed. They found several objects ranging in size from a decimeter to half a meter, which changed shape, position in the frame, appeared in some images and disappeared in others. And on a number of panoramas, precipitation was clearly observed, which fell and melted on the surface of the planet.

Жизнь, кажется, нашли. Но не там, где искали
Следуя некоторым видам поиска, мы смогли бы обнаружить жизнь, базирующуюся на совершенно ином химическом составе (без углерода и/или воды).www.nkj.ru
