NASA Selects Proposals to Study Stellar Explosions, Galaxies, Stars

NASA has selected four mission proposals submitted to the agency’s Explorers Program for further study. The proposals include missions that would study exploding stars, distant clusters of galaxies, and nearby galaxies and stars. Two Astrophysics Medium Explorer missions and two Explorer Missions of Opportunity have been selected to conduct mission concept studies. After detailed evaluation […]

NASA Helps Decipher How Some Distant Planets Have Clouds of Sand

NASA Helps Decipher How Some Distant Planets Have Clouds of Sand

A new study using archival observations by the now-retired Spitzer Space Telescope found a common trait among distant worlds where the exotic clouds form. Most clouds on Earth are made of water, but beyond our planet they come in many chemical varieties. The top of Jupiter’s atmosphere, for example, is blanketed in yellow-hued clouds made of […]

NASA Telescope to Help Untangle Galaxy Growth, Dark Matter Makeup

Nancy Grace Roman Space Telescope

NASA’s Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the apparent edges of many galaxies. Missions like the Hubble and James Webb space telescopes would have to patch together hundreds of small images to see these structures around nearby galaxies in full. Roman will do so in a […]

Hubble Captures a Galactic Dance

Hubble Captures a Galactic Dance

This NASA Hubble Space Telescope image finds the large spiral galaxy, NGC 3227, wrapped in a turbulent gravitational dance with its companion, the elliptical galaxy NGC 3226. The twosome – collectively known as Arp 94 – is relatively nearby, between 50 and 60 million light-years away toward the constellation Leo, the Lion. A close look […]

Hubble Views a Galactic Oddity

Hubble Views a Galactic Oddity

The ultra-diffuse galaxy GAMA 526784 appears as a tenuous patch of light in this image from the NASA/ESA Hubble Space Telescope. This wispy object resides in the constellation Hydra, roughly four billion light-years from Earth. Ultra-diffuse galaxies such as GAMA 526784 have a number of peculiarities. For example, they can have either very low or […]

Celebrating Hubble’s 32nd birthday with a galaxy grouping

Celebrating Hubble’s 32nd birthday with a galaxy grouping

NASA, ESA, STScI The NASA/ESA Hubble Space Telescope is celebrating its 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called the Hickson Compact Group 40. This snapshot reflects a special moment in their lifetimes as they fall together before they merge. This menagerie includes three spiral-shaped galaxies, an elliptical […]

Galaxy Collision Creates ‘Space Triangle’ in New Hubble Image

Galaxy Collision Creates 'Space Triangle' in New Hubble Image

Image Credits: NASA, ESA, STScI, Julianne Dalcanton (Center for Computational Astrophysics / Flatiron Inst. and University of Washington); Image Processing: Joseph DePasquale (STScI). Writer: Donna Weaver (STScI) A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope. The interacting galaxy duo is […]
