Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with debris. Now, in a historical milestone, NASA’s Hubble Space Telescope has directly imaged similar catastrophic […]

NASA’s Fermi Spots Young Star Cluster Blowing Gamma-Ray Bubbles
For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the universe has evolved as NASA explores the secrets of the cosmos for the benefit of all. The cluster, called Westerlund […]
NASA Announces Plan to Map Milky Way With Roman Space Telescope
NASA’s Nancy Grace Roman Space Telescope team has released detailed plans for a major survey that will reveal our home galaxy, the Milky Way, in unprecedented detail. In one month of observations spread across two years, the survey will unveil tens of billions of stars and explore previously uncharted structures. “The Galactic Plane Survey will […]
Massive Stars Make Their Mark in Hubble Image
This NASA/ESA Hubble Space Telescope image features a glittering blue dwarf galaxy called Markarian 178 (Mrk 178). The galaxy, which is substantially smaller than our own Milky Way, lies 13 million light-years away in the constellation Ursa Major (the Great Bear). Mrk 178 is one of more than 1,500 Markarian galaxies. These galaxies get their […]

NASA’s TESS Spacecraft Triples Size of Pleiades Star Cluster
Astronomers have revolutionized our understanding of a collection of stars in the northern sky called the Pleiades. They used data from NASA’s TESS (Transiting Exoplanet Survey Satellite) and other observatories as NASA explores the secrets of the universe for the benefit of all, from the Moon to Mars and beyond. By examining the rotation, chemistry, […]
NASA’s Roman Could Bring New Waves of Information on Galaxy’s Stars
Lee esta nota de prensa en español aqui. A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope. Stars’ turbulent natures produce waves that cause fluctuations in their overall brightness. By studying these […]
Webb First to Show 4 Dust Shells ‘Spiraling’ Apep, Limits Long Orbit
NASA’s James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost transparent, at the edges of Webb’s image.) Observations taken prior to Webb only detected one shell, […]

Hubble Studies Star Ages in Colorful Galaxy
Stars of all ages are on display in this NASA/ESA Hubble Space Telescope image of the sparkling spiral galaxy called NGC 6000, located 102 million light-years away in the constellation Scorpius. NGC 6000 has a glowing yellow center and glittering blue outskirts. These colors reflect differences in the average ages, masses, and temperatures of the […]
