Astronomers find missing link in massive black hole formation

Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, that black hole is the best candidate for a class of black holes astronomers have long believed to exist: intermediate-mass black holes, formed in the early stages of galaxy evolution.

Pillars of Creation Star in New Visualization from NASA’s Hubble and Webb Telescope

Combining data from NASA’s Hubble and James Webb space telescopes, a team from NASA’s Universe of Learning at the Space Telescope Science Institute (STScI) in Baltimore, Maryland has produced a breathtaking new 3D visualization of the towering “Pillars of Creation” in the Eagle Nebula.

Hubble Celebrates 34th Anniversary with a Look at the Little Dumbbell Nebula

To celebrate Hubble’s 34th launch anniversary, NASA released the telescope’s new observation of the Little Dumbbell Nebula. Also known as Messier 76, or M76, it is composed of a ring, seen edge-on as the central bar structure, where a central red giant star burned out, and two lobes of gas and dust that are on either opening of the ring.

Hubble Goes Hunting for Small Main Belt Asteroids

Astronomers and volunteer citizen scientists used Hubble’s unique capabilities to identify a largely unseen population of very small asteroids. The treasure hunt required perusing 37,000 archived Hubble images spanning 19 years. The payoff? Finding 1,701 asteroid trails, with 1,031 of the asteroids previously uncatalogued. About 400 of these uncatalogued asteroids are smaller than 1 kilometer.

Hubble Captures Movie of DART Asteroid Impact Debris

A time-lapse movie from the Hubble Space Telescope captures the impact of asteroid Dimorphos when it was deliberately hit by NASA’s DART spacecraft on Sept. 26, 2022. The movie shows three overlapping stages of the impact aftermath: the formation of an ejecta cone; the spiral swirl of debris caught up along the asteroid’s orbit about its companion asteroid; and the tail swept behind the asteroid by the pressure of sunlight. Later on, Hubble records the tail splitting in two.

HUBBLE FINDS THAT GHOST LIGHT AMONG GALAXIES STRETCHES FAR BACK IN TIME

These are Hubble Space Telescope images of two massive clusters of galaxies. The artificially added blue color is translated from Hubble data that captured a phenomenon called intracluster light. This extremely faint glow traces a smooth distribution of light from wandering stars scattered across the cluster. Billions of years ago, the stars were shed from their parent galaxies and now drift through intergalactic space alone.

Hubble Detects Protective Shield Defending a Pair of Dwarf Galaxies

Researchers have used Hubble and FUSE observations of ultraviolet light from quasars to detect and map the Magellanic Corona, a diffuse halo of hot, supercharged gas surrounding the Small and Large Magellanic Clouds. Shown in purple, the corona stretches more than 100,000 light-years from the main mass of stars, gas, and dust that make up the Magellanic Clouds, intermingling with the hotter and more extensive Milky Way Corona, shown in blue. The corona is thought to act as a buffer protecting the dwarf galaxies’ vital star-forming gas from the gravitational pull of the much larger Milky Way.

Hubble Snapshot of ‘Molten Ring’ Galaxy Prompts New Research

In this image, a remote galaxy is greatly magnified and distorted by the effects of gravitationally warped space. After its public release, astronomers used the picture to measure the galaxy’s distance of 9.4 billion light-years. This places the galaxy at the peak epoch of star formation in cosmic evolution.

Hubble Finds First Evidence of Water Vapor at Jupiter’s Moon Ganymede

Located ½-billion miles from the Sun, the water ice on Ganymede’s surface is frozen solid in frigid temperatures as low as minus 300 degrees Fahrenheit. This makes the ice as hard as rock. Still, a rain of charged particles from the Sun is enough to turn the ice into water vapor at high noon on Ganymede. This is the first time such evidence has been found, courtesy of the Hubble Space Telescope’s spectroscopic observations of aurora on Ganymede spanning two decades. The auroras are used to trace the presence of oxygen, which then is linked to the presence of water molecules sputtering off the surface. Ganymede has a deep ocean located an estimated 100 miles below the surface.

Rutgers Expert Available to Discuss James Webb Space Telescope Science

New Brunswick, N.J. (Feb. 22, 2021) – Rutgers University–New Brunswick Professor Kristen McQuinn is available for interviews on the upcoming launch of the James Webb Space Telescope, its potential scientific impact and the leap forward it will provide in our understanding of the…

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.

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.

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.
