JWST has found the oldest galaxy we have ever seen in the universe

Image

$1:
Just weeks into its mission, the James Webb Space Telescope (JWST) has broken the record for the oldest galaxy ever observed by nearly 100 million years.

Seeing some of the first galaxies to form after the big bang 13.8 billion years ago is one of the key goals of the JWST. When these emerged is currently unknown: the previous oldest identified galaxy, found by the Hubble Space Telescope, is called GN-z11 and dates back to 400 million years after the birth of the universe.

It's just beginning... there is so much more to come from JWST.

Russia to quit International Space Station after 2024


IIRC, this article misses an important part of the ISS functionality. The Russian portion of the station contains the thrusters that keep the station in orbit. So if the Russians leave, someone will have to know how to keep those systems running.

Lunar Reconnaissance Orbiter finds lunar pits harbor comfortable temperatures

Image

NASA-funded scientists have discovered shaded locations within pits on the Moon that always hover around a comfortable 63 F (about 17 C) using data from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft and computer modeling.

The pits, and caves to which they may lead, would make thermally stable sites for lunar exploration compared to areas at the Moon's surface, which heat up to 260 F (about 127 C) during the day and cool to minus 280 F (about minus 173 C) at night. Lunar exploration is part of NASA's goal to explore and understand the unknown in space, to inspire and benefit humanity.

Pits were first discovered on the Moon in 2009, and since then, scientists have wondered if they led to caves that could be explored or used as shelters. The pits or caves would also offer some protection from cosmic rays, solar radiation and micrometeorites.

"About 16 of the more than 200 pits are probably collapsed lava tubes," said Tyler Horvath, a doctoral student in planetary science at the University of California, Los Angeles, who led the new research, recently published in the journal Geophysical Research Letters.

Hubble sees supergiant Betelgeuse slowly recovering after blowing its top

Image

Analyzing data from NASA's Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME). This is something never before seen in a normal star's behavior.

The sun routinely blows off parts of its tenuous outer atmosphere, the corona, in an event known as a Coronal Mass Ejection (CME). But the Betelgeuse SME blasted off 400 billion times as much mass as a typical CME.

The monster star is still slowly recovering from this catastrophic upheaval. "Betelgeuse continues doing some very unusual things right now; the interior is sort of bouncing," says Andrea Dupree of the Center for Astrophysics | Harvard & Smithsonian.
