Hubble Captures Movie of DART Asteroid Impact Debris

March 01, 2023Release ID: 2023-006

Never-Before-Seen Spacecraft Collision Yields Unexpected Surprises

Graphic titled "Didymos-Dimorphos System" with three labeled images stacked vertically. All three images show a bright white spot in the center surrounded by an irregular cloud of blue that decreases in brightness with distance from the bright spot. The size and shape of the blue cloud are different in each image, as are the labels. In all three images the background is black and there are subtle diffraction spikes radiating from the bright spot.

Hubble Captures the Start of a New Spoke Season at Saturn

February 09, 2023Release ID: 2023-005

Mysterious Features Were First Seen Decades Ago by Voyager Spacecraft

Planet Saturn with bright white rings and multi-colored main sphere. Spoke features on the left side of the rings appear like faint gray smudges against the rings' bright backdrop, about midway from the planet to the rings' outer edge. Above the rings plane, the planet's bands are shades of red and orange, with brighter yellow nearer the equator.

For the First Time Hubble Directly Measures Mass of a Lone White Dwarf

February 02, 2023Release ID: 2023-004

Astronomers Use a Trick of Nature to 'Weigh' a Dead Star

Diagram titled “Hubble measures deflection of starlight by a foreground object.” Diagram includes an illustration of the Hubble Space Telescope observing a distant star whose light curves around another object—a white dwarf star—in the foreground. The diagram shows the real position of the observed star, the light path of that star, and the apparent (“observed”) position of the star. The white dwarf is in the center of the diagram, on a grid that appears to be warped downward under the enormous mass of the white dwarf. Hubble is toward the lower right on the diagram, at the 5 o’clock position relative to the white dwarf. It is pointing up toward the 12 o’clock position, where the star appears to be (“observed star position”). A straight dashed line connects the observed star position with the telescope. The real star position is at 11 o’clock. A solid line curves from the real star position, around the white dwarf, to the telescope.

Hubble Finds Hungry Black Hole Twisting Captured Star Into Donut Shape

A Deep Gravitational Sinkhole Swallows Unlucky Bypassing Star

Four-panel illustration titled "Black Hole Devours Bypassing Star" showing four stages of a star being shredded by a black hole.

Hubble Finds that Ghost Light Among Galaxies Stretches Far Back in Time

January 04, 2023Release ID: 2023-003

Orphaned Stars Were Lost into Intergalactic Space Long Ago

Two side-by-side images showing dozens of galaxies of different colors, shapes, and sizes. At the center of each image is a cluster of galaxies within a ghostly blue light.

Peekaboo! A Tiny, Hidden Galaxy Provides a Peek into the Past

December 06, 2022Release ID: 2022-051

Tucked away in a local pocket of dark matter, a late-blooming dwarf galaxy looks like it belongs in the early universe.

A large bright star is centered, with four long rays extending in an X shape. Between the rays on the right is a small blue peanut-shaped galaxy with some bright spots. Smaller similar stars and orange background galaxies fill image.

Hubble Captures 3 Faces of Evolving Supernova in Early Universe

November 09, 2022Release ID: 2022-054

Blast from the Past Caught in Episodes Due to Gravitational Lensing

The left panel shows the portion of Abell 370 where the multiple images of the supernova appeared. Panel A, a composite of Hubble observations from 2011 to 2016, shows the locations of the multiply imaged host galaxy after the supernova faded. Panel B, a Hubble picture from December 2010, shows the three images of the host galaxy and the supernova at different phases in its evolution. Panel C, which subtracts the image in Panel B from that in Panel A, shows three different faces of the evolving supernova. Using a similar image subtraction process for multiple filters of data, Panel D shows the different colors of the cooling supernova at three different stages in its evolution.

How NASA’s Roman Telescope Will Scan for Showstopping Explosions

November 03, 2022Release ID: 2022-049

Roman is set to help researchers detect more kilonovae, helping us learn significantly more about these “all-star” smashups.

Two bright blue circular shapes that appear to be joined are left of center. They are illustrations of neutron stars merging. Debris, which is also white and bright blue, emanates in misshapen patterns primarily from where they are joining at the center.

NASA’s Hubble Spots Twin Tails in New Image After DART Impact

October 20, 2022Release ID: 2022-056

Aftermath of First-of-Its-Kind Test Intrigues Astronomers

A bright blue spot is at the left-center of the image, which has a black background. The spot is the Didymos-Dimorphos system after impact from the DART spacecraft. The center bright spot has 3 diffraction spikes extending from its core at the 1 o’clock, 7 o’clock, and 10 o’clock positions. There is a small amount of dusty haze just below the southern pole of the center dot. Two tails of ejecta that appear as white streams of material extend out from the center at the 2 o’clock and 3 o’clock positions.

Illustration showing two neutron stars colliding with each other, producing a bright jet and gravitational waves.

Webb, Hubble Capture Detailed Views of DART Impact

September 29, 2022Release ID: 2022-047

First Time Webb, Hubble Make Simultaneous Observations of the Same Target

Image is three columns, each column is a photo with a black background, a bright blue spot is at center. In the panel column all the way to the left, noted as 22 minutes after impact, the center bright spot only has a small amount of dusty haze and only a few spikes closely surrounding it.In the middle column, noted as 5 hours after impact, the haze around the blue dot has expanded wider out with additional spikes and haze.In the column to the left, noted as 8.2 hours after impact, the haze around the blue dot spreads even further, with wisps expanding to the bottom left of the image.
