Astronomers used cosmic explosions to find that we may be wrong about our own galaxy. O recorte ajuda a contextualizar a pauta dentro de Lifestyle.

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from

Blue and white stars shine brilliantly against a crimson background of glowing gas in this July 3, 2026, image of stellar nursery LH 95 from NASA’s Hubble Space Telescope. LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. Low-mass infant s

For the first time, astronomers have directly mapped the magnetic field surrounding one of the Milky Way's most unusual pulsars, confirming a decades-old prediction about how particles stream away from the rapidly spinning stellar corpse.

For just one day, our dark universe detective, Euclid, turned its gaze toward the light: the extremely bright inner region of our Milky Way galaxy, known as the galactic bulge. This special request came from astronomers who were after what Euclid does best: capturing huge areas o

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

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing t

The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance to these echoes, they found the outer arms to be up

More than 500,000 stars blaze red, white, and blue in this image from NASA's Hubble Space Telescope, released in celebration of the United States' 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy's most massive globular clusters, or spherical col

NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped transform the young universe in

Celebrating the United States' 250th anniversary, NASA released a stunning Hubble portrait of Messier 3, an ancient globular cluster with more than 500,000 stars. The remarkable cluster is helping scientists unravel the Milky Way's past thanks to its rare stars and possible origi

Where would you go to watch a star being born? Probably not the heart of the Milky Way, which is about the most violent neighborhood our galaxy has to offer, a maelstrom of gas churning so fast and so chaotically that you would think nothing could ever settle there long enough to
