Proposed constellations of orbiting mirrors and data centers would completely destroy the night sky as humanity has known it for millions of years, experts say.
AI could soon be able to hijack satellites and cause them to collide with other spacecraft, triggering a cascade that could render Earth orbit unsafe.
SpaceX's plan to launch one million orbiting data centers to space worries astronomers, who say the satellite streaks caused by the proposed constellation would severely impair observations.
A meteorite has crashed through the roof of a house after thousands observed a stunning fireball streak across the sky in western Europe.
The world's first commercial space telescope has released its first image as it begins its journey to help track nearby stars that might host habitable exoplanets.
The sun's visible disk has been perfectly free from sunspots for the first time since June 2022, suggesting the current solar cycle might be heading toward its quieter phase.
For the first time ever, scientists have observed in near real time a cloud of air pollution created as a SpaceX rocket burned up in Earth's atmosphere.
The UK government is to slash by 30 percent its funding for astronomy, particle and nuclear physics in a move branded as disastrous for the field and likely to affect a generation of researchers.
A light-polluting green hydrogen plant project that would seriously affect one of the world's most important astronomical observatories has been scrapped by the company behind it.
The satellites in Amazon's new internet-beaming megaconstellation in low Earth orbit are bright enough to disrupt astronomical research, a study has found.
Earthquake sensors can detect sonic booms generated by reentering space debris to help track the potentially dangerous objects in near real time.
A recent string of cyberattacks against the European Space Agency is just the tip of the iceberg, a researcher said, claiming that email credentials of ESA employees are regularly leaked online.
Reference Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios).
A California-based start-up wants to open a hotel on the moon by 2032 and is now accepting bookings for the out-of-this world travel experience.
"We are in constant contact with NASA."
Such experiments have previously only been conducted aboard the International Space Station.

Satellites would likely begin colliding with each other or space junk in less than three days if they were to lose the ability to maneuver, for example due to an intense solar storm.
"We might lose the ability to observe about 30% of the faintest galaxies. We are at the point of starting to be able to see details of exoplanet atmospheres, but if the sky gets brighter, we may not be able to see those details anymore."
An AI start-up has found a vulnerability in security software protecting NASA's ground control communications with satellites in space.
Levels of potentially dangerous cosmic radiation in Earth's atmosphere rose to a two-decade high in November after a rare solar super-flare pummeled the planet with high-speed particles from the sun.
A cosmic ray from a faraway supernova explosion may have sent a packed passenger jet into free fall in late October, forcing an emergency landing.
The European Space Agency member states have approved a record-breaking budget for the next three years, including increased funding for science exploration.
