The universe is haunted by “cosmic ghosts” called neutrinos, which seem to be the “whispers” of stars that died in supernova explosions over the course of billions of years.
When some stars die, they do not do so alone, potentially solving a long-standing mystery around a particular class of cosmic explosion called an interacting supernova.
Astronomers have detected radio signals coming from a long-dead neutron star known as the ‘Blue Eye Pulsar’ after searching for decades.
Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.
Blue and white stars shine brightly against crimson gas in this image from NASA’s Hubble Space Telescope.
More than 500,000 stars blaze red, white, and blue in this NASA Hubble image of the globular cluster Messier 3 (M3).
“It’s like using a time machine to peer into the distant future of our solar system.”
The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be […]
A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA’s Nancy Grace Roman Space Telescope, launching later this summer. This sneak peek gives astronomers a major jumpstart on a core Roman survey, helping scientists […]
Terzan 5 is a globular cluster with some unusual properties that have led a team of astronomers to suspect that it is more than meets the eye.
