NASA joins telescope, instruments to Roman spacecraft

Technicians have successfully integrated NASA's Nancy Grace Roman Space Telescope's payload—the telescope, instrument carrier, and two instruments—to the spacecraft that will deliver the observatory to its place in space ...

Gamma-ray outburst detected from the radio source 3C 216

Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported ...

Will Comet G3 ATLAS perform at perihelion?

What "may" be the best anticipated comet of 2025 is coming right up. Right now, there's only one comet with real potential to reach naked eye visibility in 2025: Comet C/2024 G3 ATLAS. This comet reaches perihelion at 0.094 ...

Physicists explain a stellar stream's distinctive features

Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky Way, known for its long, thin structure, and unusual ...

Fast radio burst confirmed to originate from neutron star

Fast radio bursts (FRBs) are notoriously difficult to study. They are flashes of radio light that can outshine a galaxy but often last for only a fraction of a second. For years, all we could do was observe them by random ...

Video: See and hear three years of solar fireworks

At the start of this new year, we look back at close-up pictures and solar flare data recorded by the ESA-led Solar Orbiter mission over the last three years. See and hear for yourself how the number of flares and their intensity ...

A treasure trove of unseen stars beyond the 'Dragon Arc'

Looking halfway across the observable universe and expecting to see individual stars is considered a non-starter in astronomy, a bit like raising a pair of binoculars at the moon in hopes of making out individual grains of ...

Hubble captures a pale blue supernova in galaxy LEDA 22057

This NASA/ESA Hubble Space Telescope Picture of the Week features the galaxy LEDA 22057, which is located about 650 million light-years away in the constellation Gemini. Like the subject of a previous Picture of the Week, ...
