When Silence Becomes the Story. Three weeks after the “blue-light anomaly,” the absence of data has turned 3I/ATLAS from a scientific curiosity into a test of institutional trust. Over the past few ...

A pair of quasars that existed when the universe was only 3 billion years old has been spotted by the Hubble Space Telescope.

In about 5 billion years, our Sun will run out of hydrogen fuel and collapse into a dense, Earth-sized remnant called a white dwarf. Though it will no longer shine as it once did, this stellar core ...

A massive comet known as 3I/ATLAS that was first discovered zooming across the solar system over the summer showed signs of ...

An interstellar comet that originated outside our solar system just made its closest pass of the sun, setting it on an outgoing path — but it’s not leaving our cosmic ...

While to some 3I/Atlas is simply a weird-acting exocomet of unusual composition, others, such as Dr Avi Loeb of Harvard University, propose that we should consider the possibility that it is an ...

Using the James Webb Space Telescope, astronomers have captured the clearest picture yet of how galaxies formed in the early universe.

Astronomers discover a 3-billion-year-old white dwarf, LSPM J0207+3331, actively accumulationplanetary material long after its star’s death, revealing ongoing dynamics in ancient stellar remnants.

Of the three November meteor showers, Leonids should be the most active. It is fed by the Tempel-Tuttle Comet, which can produce some dense debris clouds, resulting in very strong showers. Leonids is ...

If it is a galaxy, it would be the oldest known galaxy in the cosmos, but it could also be a brown dwarf or an early black hole.

The James Webb Space Telescope has captured imagery of spiral galaxy NGC 7469, which is 90,000 light-years in diameter. The ...
