Hubble Snapshot of ‘Molten Ring’ Galaxy Prompts New Research
In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep-space optical phenomenon dubbed an “Einstein ring.” The photo was released in…
Mapping the Universe’s Earliest Structures with COSMOS-Webb
When NASA’s James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe. Called…
Dark matter is slowing the spin of the Milky Way’s galactic bar
For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured.
A study shows the unexpected effect of black holes beyond their own galaxies
These results suggest, then, that there is a particular coupling between the black holes and their galaxies, by which they can expel matter to great distances from the galactic centres,…
Peering into a Galaxy’s Dusty Core to Study an Active Supermassive Black Hole
What, precisely, is happening at its core to cause all this activity? Upcoming observations led by Nora Lützgendorf and Macarena García Marín of the European Space Agency using NASA’s James…
Magnetic ‘Highway’ Channels Material Out of Cigar Galaxy
Located 12 million light-years from Earth in the constellation Ursa Major, the Cigar galaxy is undergoing an exceptionally high rate of star formation called a starburst. The star formation is…
Hubble Views a Galactic Waterfall
Interacting galaxies, such as these, are so named because of the influence they have on each other, which may eventually result in a merger or a unique formation. Already, these…
Chandra Data Tests ‘Theory of Everything’
March 19, 2020 One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably…
Galactic Pyrotechnics From 23 Million Light Years Away
From NASA Dec. 31, 2019 Galactic Pyrotechnics From 23 Million Light Years Away A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than…
Hubble’s Close-Up of Spiral’s Disk, Bulge
From NASA Dec. 20, 2019 This image from the NASA/ESA Hubble Space Telescope shows IC 2051, a galaxy in the southern constellation of Mensa (the Table Mountain) lying about 85…

From NASA Dec. 13, 2019 Hubble Views Galaxy’s Dazzling Display The galaxy is the eponymous member of the NGC 3175 group, which has been called a nearby analog for the…
Hubble Finds Medusa in the Sky
From NASA Oct. 24, 2019 Hubble Finds Medusa in the Sky Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one…
Hubble Spots Stunning Spiral Galaxy
From NASA May 3, 2019 Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars,…
