Hubble Uncovers Concentration of Small Black Holes
Astronomers using the Hubble Space Telescope in their hunt for a massive black hole at the heart of the globular cluster NGC 6397 found something they weren’t expecting: a concentration of smaller black holes lurking there instead. This is a new twist on the search for intermediate-mass black holes. They are the long-sought “missing link” between supermassive black holes and stellar-mass black holes.
Researchers Rewind the Clock to Calculate Age and Site of Supernova Blast
Hubble astronomers have retraced the expanding gaseous debris from a nearby exploded star to estimate the location and time of the stellar detonation. Their analysis reveals that the light from the supernova blast reached Earth about 1,700 years ago.
Dark Storm on Neptune Reverses Direction, Possibly Shedding a Fragment
A giant dark storm on Neptune heading for certain doom at the equator mysteriously halted its journey and began drifting in the opposite direction. Almost simultaneously, another smaller dark spot appeared nearby, only to vanish months later. Hubble astronomers are presenting these findings today at the Fall 2020 American Geophysical Union meeting.
Hubble Pins Down Weird Exoplanet with Far-Flung Orbit
Astronomers analyzing Hubble images of the double star, HD 106906, have discovered a planet in a huge 15,000-year-long orbit that sweeps it as far from its stellar duo as Planet Nine would be from our Sun. This is observational evidence that similarly far-flung worlds may exist around other stars. Researchers hypothesize that the planet wound up there in a game of planetary pinball where the gravitational pull of a passing star modified the orbit’s shape.
Leaving so soon? Unusual planetary nebula fades mere decades after it arrived
Using images from the Hubble Space Telescope, astronomers have discovered that the Stingray Nebula, the youngest planetary nebula in our sky, has faded dramatically over the course of just 20 years. If dimming continues at current rates, in 20 or 30 years the Stingray Nebula will be barely perceptible.
Hubble Catches Possible ‘Shadow Play’ of the Disk Around a Black Hole
This Hubble image of a disk of material feeding a monster black hole in nearby galaxy IC 5063 may be casting its shadow into space. The shadow is interspersed with bright rays that extend across the galaxy. This unique effect offers insight into the structure of the disk.
NASA’s Hubble Sees Unexplained Brightness from Colossal Explosion
Following up on an enormous gamma ray burst detected by Swift in May, Hubble astronomers believe they’ve viewed the glow of a kilonova, the aftermath of a colossal explosion caused by the merger of two neutron stars that formed a magnetar. The near-infrared emission seen by Hubble was 10 times brighter than predicted.
Hubble Launches Large Ultraviolet-Light Survey of Nearby Stars
This is a ground-based telescopic photo of the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The LMC is one of several select targets of a new initiative with NASA’s Hubble Space Telescope, called ULLYSES (UV Legacy Library of Young Stars as Essential Standards). The program is looking at over 300 stars to build an ultraviolet-light catalog for capturing the diversity of stars, from young to old, to give astronomers a much better understanding of the birth of stars and how this relates to everything from planets to the formation and evolution of galaxies.
Hubble Finds “Greater Pumpkin” Galaxy Pair
This new Hubble photo resembling a Halloween carved pumpkin features the early stages of a collision between two galaxies. The “pumpkin’s” glowing “eyes” are the bright, star-filled cores of each galaxy that contain supermassive black holes. An arm of newly forming stars give the imaginary gourd a wry smirk.
Hubble Watches Exploding Star Fade into Oblivion
Hubble Space Telescope images have been assembled into a time-lapse video of an exploding star fading into oblivion inside a distant galaxy. The video compresses one-year’s worth of observations into seconds. When it exploded the supernova was as bright as 5 billion Suns.
Hubble Captures Crisp New Portrait of Jupiter’s Storms
More massive than all the other planets combined, Jupiter truly is the king of our solar system. The swirling clouds, arranged in colorful, banded structures, change from year to year. The rich colors are produced by trace compounds in Jupiter’s predominantly hydrogen/helium atmosphere. Hurricane-force winds propel these clouds, and upwelling currents are ablaze with lightning bolts far more powerful than those seen on Earth.
The Hubble Space Telescope serves as a “weather satellite” for monitoring Jupiter’s stormy weather. The iconic Great Red Spot, a storm big enough to swallow Earth, shows that it’s shrinking a little in the Hubble images, but it still dominates the entire southern atmosphere, plowing through the clouds like a cargo ship.
Hubble astronomers patiently wait to get close-up snapshots as Earth make its nearest annual approach to Jupiter – an astronomical alignment called an opposition, when Jupiter is on the opposite side of the Earth from the Sun.
Hubble Observations Suggest a Missing Ingredient in Dark Matter Theories
Astronomers using Hubble and the VLT have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why they have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new findings indicate that small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.
Hubble Finds that Betelgeuse’s Mysterious Dimming Is Due to a Traumatic Outburst
Hubble Space Telescope observations show that the unexpected dimming of supergiant star Betelgeuse was probably caused by an immense amount of hot plasma ejected into space. The plasma cooled, forming a dust cloud that blocked starlight coming from Betelgeuse’s surface.
Hubble Uses Earth as a Proxy for Identifying Oxygen on Potentially Habitable Planets Around Other Stars
Astronomers used Hubble during a total lunar eclipse to detect ozone in our planet’s atmosphere by looking at Earthlight reflected off the Moon in ultraviolet wavelengths. This method serves as a proxy for how astronomers will observe Earth-like exoplanets in search of life.
Hubble Sees Summertime on Saturn
Hubble photographed Saturn and its rings on July 4, during summer in Saturn’s northern hemisphere. This image is taken as part of the Outer Planets Atmospheres Legacy (OPAL) project. OPAL is helping scientists understand the atmospheric dynamics and evolution of our solar system’s gas giant planets.

Intense Flash from Milky Way’s Black Hole Illuminated Gas Far Outside of Our Galaxy
Not long ago, the center of our galaxy exploded. Our primitive ancestors, already afoot in Africa, probably saw the resulting flare. Now Hubble detects that flash’s signature in a huge tail of gas orbiting the galaxy some 200,000 light-years away.
In Planet Formation, It’s Location, Location, Location
When it comes to the best region to form planets, it’s all about location. Planets in the nearby star cluster Westerlund 2 may have a rough time forming in the crowded core. Astronomers using Hubble find that energy from hefty stars is blowing away planet-forming dust clouds from smaller stars.
Seeing the Universe Through New Lenses
Like crystal balls for the universe’s deeper mysteries, galaxies and other massive space objects can serve as lenses to more distant objects and phenomena along the same path, bending light in revelatory ways. Gravitational lensing was first theorized by Albert…

No Blue Skies for Super-Hot Planet WASP-79b
Combined observations of WASP-79b from Hubble and other telescopes reveal a weird super-hot planet where the sky is yellow instead of blue due to lack of an atmospheric effect called Rayleigh scattering, which makes Earth’s sky blue.

This pair of Hubble photos of comet C/2019 Y4 (ATLAS), taken on April 20 and 23, 2020, provide the sharpest views yet of the breakup of the solid nucleus of the comet. Hubble distinguishes as many as 30 pieces that are roughly the size of a house.
Extrasolar Planet Apparently Disappears in Latest Hubble Observations
Astronomers using the Hubble Space Telescope have come to the jaw-dropping conclusion that a planet orbiting another star has seemingly disappeared after appearing in several years’ worth of Hubble images. A team of astronomers from the University of Arizona believe this is forensic evidence of a titanic collision between two asteroid-sized bodies orbiting a nearby star, Fomalhaut.
