ALMA Discovers Massive Rotating Disk in Early Universe
National Radio Astronomy Observatory

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation. This research appears on 20 May 2020 in the journal Nature.

Hubble Marks 30 Years in Space with Tapestry of Blazing Starbirth
Space Telescope Science Institute (STScI)

A colorful image resembling a cosmic version of an undersea world teeming with stars is being released to commemorate the Hubble Space Telescope's 30 years of viewing the wonders of space.

Piercing the Dark Birthplaces of Massive Stars with Webb
Space Telescope Science Institute (STScI)

Scientists will use NASA's James Webb Space Telescope study three mysterious, cold, dense clouds where high-mass stars form.

Hubble Finds Best Evidence for Elusive Mid-Sized Black Hole
Space Telescope Science Institute (STScI)

A team of astronomers have found the best evidence yet that the culprit in a stellar homicide is a mid-sized black hole, the long-sought "missing link" in the black hole family. Multiple lines of evidence pointed to the elusive type of black hole, including investigations using Hubble and Chandra.

Beyond the Brim, Sombrero Galaxy's Halo Suggests a Turbulent Past
Space Telescope Science Institute (STScI)

Hubble Space Telescope observations suggest that the broad "brim" of the Sombrero galaxy may conceal a turbulent past. Clues to a rough-and tumble history lie in the galaxy's extended halo.

Hubble Detects Smallest Known Dark Matter Clumps
Space Telescope Science Institute (STScI)

Using Hubble and a new observing technique, astronomers have uncovered the smallest clumps of dark matter ever detected. Dark matter is an invisible substance that makes up most of the universe's mass and forms the scaffolding upon which galaxies are built.

Fast Radio Burst Observations Deepen Astronomical Mystery
Association of Universities for Research in Astronomy (AURA)

Observations with the 8-meter Gemini North telescope, a program of the NSF’s National Optical-Infrared Astronomy Research Laboratory, have allowed astronomers to pinpoint the location of a Fast Radio Burst in a nearby galaxy — making it the closest known example to Earth and only the second repeating burst source to have its location pinpointed in the sky. The source of this burst of radio waves is located in an environment radically different from that seen in previous studies. This discovery challenges researchers’ assumptions on the origin of these already enigmatic extragalactic events.

NASA's Hubble Surveys Gigantic Galaxy
Space Telescope Science Institute (STScI)

Hubble has photographed a majestic spiral galaxy, UGC 2885, located 232 million light-years away. The galaxy is 2.5 times wider than our Milky Way and contains 10 times as many stars. Astronomers want to know how it got so big.

'Cotton Candy' Planet Mysteries Unravel in New Hubble Observations
Space Telescope Science Institute (STScI)

Astronomers using Hubble have studied a unique class of young, migratory exoplanets that have the density of cotton candy. Nothing like them exists in our solar system. They orbit the star Kepler 51, located 2,600 light-years away. Hubble spectroscopic observations allowed researchers to refine mass estimates for these worlds—independently confirming their “puffy” nature.

Astronomers Propose a Novel Method of Finding Atmospheres on Rocky Worlds
Space Telescope Science Institute (STScI)

A team of astronomers proposes a new method of using Webb to determine whether a rocky exoplanet has an atmosphere. The technique, which involves measuring the planet’s temperature as it passes behind its star and then comes back into view, is significantly faster than more traditional methods of atmospheric detection.
