Hubble Hooks a Supernova Host Galaxy

This unbalanced the star and triggered runaway nuclear fusion that eventually led to an intensely violent supernova explosion. The supernova shone brightly for quite some time and was easily visible from Earth through even a small telescope until months later.

Hubble Finds Best Evidence for Elusive Mid-Sized Black Hole

From NASA March 31, 2020 Astronomers have found the best evidence for the perpetrator of a cosmic homicide: a black hole of an elusive class known as “intermediate-mass,” which betrayed its existence by tearing apart a wayward star that passed too close. Weighing in at about 50,000 times the mass of our Sun, the black…

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 paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas. This galactic fireworks display is…

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 million light-years away. It is a spiral galaxy, as evidenced by its characteristic whirling, pinwheeling arms, and it has a bar of stars slicing through…

New clues on dark matter from the darkest galaxies

A study by SISSA provides important information on its composition and on its interaction with luminous matter Scuola Internazionale Superiore di Studi Avanzati They are called low-surface-brightness galaxies and it is thanks to them that important confirmations and new information have been obtained on one of the largest mysteries of the cosmos: dark matter. “We…

Hubble Views Galaxy’s Dazzling Display

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 Local Group. The Local Group contains our very own home galaxy, the Milky Way, and around 50 others — a mix of spiral, irregular and…

Hubble studies gamma-ray burst with highest energy ever seen

NASA/Goddard Space Flight Center NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe — a blast of gamma-rays a trillion times more powerful than visible light. That’s because in a few seconds the gamma-ray burst (GRB) emitted more energy than the Sun…

Hubble Spots a Curious Spiral

From NASA Nov. 15, 2019 Hubble Spots a Curious Spiral The universe is simply so vast that it can be difficult to maintain a sense of scale. Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively similar: spiraling arms, a glowing center, and…
