The stars move across the night sky, over long periods like 10 years, and short periods of around six months.

The James Webb Space Telescope has discovered a massive chain of 20 galaxies in the early universe, raising questions about the formation of the largest structures in the cosmos.
Greg Brockman, OpenAI co-founder, is also joining Microsoft to lead a new advanced AI research team.
Microsoft is hiring former OpenAI CEO Sam Altman and co-founder Greg Brockman.
Altman was fired from OpenAI on Friday, after the board said it “no longer has confidence in his ability to continue leading OpenAI.” After a weekend of negotiations to potentially bring Altman back to OpenAI, Microsoft CEO Satya Nadella announced that both Sam Altman and Greg Brockman will be joining to lead Microsoft’s new advanced AI research team.
“We’re extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” says Nadella. “We look forward to moving quickly to provide them with the resources needed for their success.”
Researchers created a quantum gas containing two types of atoms on the ISS, in a first for space-based research.
In the very early universe, physics were weird. A process known as inflation, during which the universe went from a single infinitesimal point to everything we see today, was one such instance of those weird physics. Now, scientists from the Chinese Academy of Science have sifted through 15 years of pulsar timing data in order to put some constraints on what physics looks like.
The 15 years of data come from the North American Nanohertz Observatory for Gravitational Waves or NANOGrav’s goal is to use an unconventional way to detect gravitational waves —by looking at pulsars. These fast-spinning objects are commonly used as “clocks” in astronomical terms.
Back in 1983, a pair of astronomers (Ronald Hellings and George Downs) developed a method by which astronomers could use an array of these pulsars to check for shifts that gravitational waves might cause.
Using the James Webb Space Telescope, an international team, including astronomer Alexander de la Vega of the University of California, Riverside, has discovered the most distant barred spiral galaxy similar to the Milky Way that has been observed to date.
Until now it was believed that barred spiral galaxies like the Milky Way could not be observed before the universe, estimated to be 13.8 billion years old, reached half of its current age.
The research, published in Nature this week, was led by scientists at the Centro de Astrobiología in Spain.
Thanks to the Hubble Space Telescopes, astronomers can confirm that there’s a rocky exoplanet just a couple dozen light years away.
Mira Murati is to temporarily take up the reins at OpenAI following Sam Altman’s surprising departure.
After Sam Altman’s surprise sacking from OpenAI on Friday, the AI company has announced that Mira Murati will fill the gap as interim Chief Executive Officer (CEO) until a replacement is found. A relative unknown outside of Silicon Valley, many interested in the artificial intelligence (AI) space are rightfully wondering who she is. Let’s find out what we know so far.

The “Cosmic Vine” is a massive structure in the cosmic web that links 20 galaxies in the early universe.
