The new AI system can estimate cosmological parameters with stunning precision, and it could help astronomers unpick one of the thorniest problems in the field.

Astronomers from the Special Astrophysical Observatory (SAO) in Russia and elsewhere report the discovery of a new cataclysmic variable system, designated SRGe J194401.8+284452, which is located some 1,350 light years away. The finding was detailed in a research paper published August 26 on the pre-print server arXiv.

A Space Force officer will command a mission later this month to safely bring home two astronauts who have been unexpectedly stuck aboard the International Space Station, or ISS, marking the first time a Guardian will launch into space for such a high-profile operation.

Col. Nick Hague, an active-duty Space Force Guardian, will be joined by Roscosmos cosmonaut Aleksandr Gorbunov aboard the SpaceX Dragon spacecraft for NASA’s Crew-9 mission. Originally, Hague and Gorbunov were supposed to be joined by two other astronauts for a trip to space, but problems with the Boeing Starliner spacecraft that have left astronauts Barry Wilmore and Sunita Williams stuck aboard the space station for months longer than anticipated shifted the mission objective, date and staffing.

Hague and Gorbunov will launch no earlier than Sept. 24, NASA said in a Friday news release, and will return to Earth with Wilmore and Williams in February 2025. The Guardian and the cosmonaut were chosen for their particular experience and skill sets, the agency said.

This belief is slightly paradoxical as we have zero evidence that aliens even exist. What’s more, given the vast distances between star systems, it seems odd we’d only learn about them from a visit. Evidence for aliens is more likely to come from signals from faraway planets.

In a paper accepted for publication in the Proceedings of the International Astronomical Union, I argue that the belief in alien visitors is no longer a quirk, but a widespread societal problem.

This week Brits will be able to see Saturn as enters opposition, find out how and when and stargazing tips.

A small team of engineers and geophysicists from Northwestern University, the University of Chicago, and the University of Central Florida has found, via modeling, that creating millions of metal nanorods from material on the Martian surface and then blasting them into the atmosphere would be a more efficient way to heat the planet than generating greenhouse gases. Their paper is published in the journal Science Advances.

Science fiction writers have for many years envisioned a future when Mars is made habitable through terraforming techniques, allowing humans to survive without the need for special buildings and spacesuits. Recently, scientists have begun looking at the possibility, though most project ideas are far less ambitious.

Instead of completely transforming the planet, many are looking at simply warming it up a bit to make it more habitable. Most such ideas have centered on releasing greenhouse gases into the atmosphere to capture more heat from the sun. Unfortunately, there are few ingredients on the Martian surface that could be used to create and release such gases.

For centuries, we thought that the Universe was completely deterministic. But even if you know all the rules, you can’t get rid of chaos.

The standard model of the universe relies on just six numbers. Using a new approach powered by artificial intelligence, researchers at the Flatiron Institute and their colleagues extracted information hidden in the distribution of galaxies to estimate the values of five of these so-called cosmological parameters with incredible precision.

Spacecraft data has confirmed successful deployment of the futuristic technology.
