Goldilocks Stars Are Best Places to Look for Life

Goldilocks Stars Are Best Places to Look for Life

01.08.2020
In looking for life beyond Earth, astronomers seek planets in stars' "habitable zones" (nicknamed the "Goldilocks zone") where temperatures are just right for life-nurturing liquid water to exist on planets' surfaces. An emerging idea is that there are "Goldilocks stars": not too hot, not too cool, not too violent to host life-friendly planets.
Hubble Detects Smallest Known Dark Matter Clumps

Hubble Detects Smallest Known Dark Matter Clumps

01.08.2020
Dark matter forms much smaller clumps than previously known. This result confirms one of the fundamental predictions of the widely accepted "cold dark matter" theory. All galaxies, according to this theory, form and are embedded within clouds of dark matter, a hard-to-detect form of matter making up the bulk of the universe's mass.

New Technique May Give NASA’s Webb Telescope a Way to Quickly Identify Planets with Oxygen

01.06.2020
Researchers may have found a way that NASA's James Webb Space Telescope can quickly identify nearby planets that could be promising for our search for life, as well as worlds that are uninhabitable because their oceans have vaporized.

NASA's Great Observatories Help Astronomers Build a 3D Visualization of an Exploded Star

01.05.2020
Astronomers and visualization specialists from the NASA's Universe of Learning program have combined the visible, infrared, and X-ray vision of NASA's Great Observatories to create a three-dimensional representation of the dynamic Crab Nebula, the tattered remains of an exploded star.
Astronomers Spot Distant Galaxy Group Driving Ancient Cosmic Makeover

Astronomers Spot Distant Galaxy Group Driving Ancient Cosmic Makeover

01.05.2020
Astronomers have found the farthest galaxy group identified to date. Called EGS77, the galaxies are participating in a sweeping cosmic makeover called reionization, which transformed the universe into what we see today.
NASA's Hubble Surveys Gigantic Galaxy

NASA's Hubble Surveys Gigantic Galaxy

01.05.2020
This majestic spiral galaxy might earn the nickname the "Godzilla Galaxy" because it may be the largest known in the local universe. The galaxy, UGC 2885, is 2.5 times wider than our Milky Way and contains 10 times as many stars.
Hubble Sights Galaxy’s Celestial Sequins

Hubble Sights Galaxy’s Celestial Sequins

01.03.2020
This smattering of celestial sequins is a spiral galaxy named NGC 4455, located in the northern constellation of Coma Berenices (Berenice’s Hair). This might sound like an odd name for a constellation — and in fact it is somewhat unusual. It’s the only modern constellation named in honor of a real person from history: Queen Berenice II of Egypt.

Hubble Spots Galaxy’s Dramatic Details

12.06.2019
Some of the most dramatic events in the universe occur when certain stars die — and explode catastrophically in the process. When these star deaths, or supernovae, occur, their brightness can rival the light of a whole galaxy. The galaxy NGC 5468, shown in this Hubble image, has hosted a number of these supernovae the past 20 years.
