Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue and green, and its top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral arms that wrap up counterclockwise.

Hubble’s Window on the Universe: NASA Celebrates Hubble’s 35th Year in Orbit

In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy ...

NSF’s Inouye Solar Telescope’s Cryo-NIRSP instrument offers unprecedented look at Alfvén waves

Over the last decade, scientists have confirmed the presence of a an important type of magnetized waves called Alfvén waves in the Sun’s outer atmosphere – i.e., the corona. These waves, specific to plasma environments ...

Graphic titled “Hubble Space Telescope – Observations of Uranus,” with 16 images of Uranus, arranged in a 4 by 4 grid showing changes in appearance of Uranus as observed by Hubble between 2002 and 2022. Columns are labeled with observation year, from left to right: 2002; 2012; 2015; and 2022. Rows are labeled from top to bottom: visible light; visible and near infrared; aerosols/haze; and methane depletion. In the visible light images in the top row, Uranus appears blue-green with faint vertical bends of slightly lighter or darker color. In the visible and near infrared images in the second row, Uranus is very colorful, with deep neon blue to neon green bands within an orange-red glow that outlines the edge of the planet. In the two bottom rows of images, Uranus appears in grayscale, with vertical bands ranging from dark gray to almost white. All four rows of images show changes from observation to observation (left to right). For a given year, all four images in the column show similar banding patterns.

20-Year Hubble Study of Uranus Yields New Atmospheric Insights

The ice-giant planet Uranus, which travels around the Sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights ...

A two-panel horizontal image. On the left is Neptune, as seen from the Hubble Space Telescope. It is a blue circle, tilted about 25 degrees to the left. There are white smudges at 7 o’clock and just above 5 o’clock. At the right is an opposing view of the planet, using data from Hubble and Webb. It is a multi-hued blue orb. There are white smudges in the same spots as the image on the left, but also at the center of the planet and at the top. There are cyan smudges vertically along the right side, with the top of the smudging more translucent than the bottom.

NASA’s Webb Captures Neptune’s Auroras For First Time

For the first time, NASA’s James Webb Space Telescope has captured bright auroral activity on Neptune. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually ...

DESI Uncovers 300 New Intermediate-Mass Black Holes Plus 2500 New Active Black Holes in Dwarf Galaxies

Within the Dark Energy Spectroscopic Instrument’s early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an active black hole, more than tripling the existing census of both ...

A large, black circle representing a black hole occupies the right third of the frame in this illustration. Thick, clumpy orange streaks arc above and below it, essentially surrounding it. The top arc extends down to the lower left and then curves around in front of the black hole to form a disk that is tilted toward the viewer. Near the inner edge of the disk, several bright, whiter spots have blue filaments looping above them, representing flares. The words “Artist’s Concept” appear in the bottom left corner in gray.

Webb Reveals Rapid-Fire Light Show From Milky Way’s Central Black Hole

The supermassive black hole at the center of the Milky Way appears to be having a party, complete with a disco ball-style light show. Using NASA’s James Webb Space Telescope, a team of astrophysicists has ...

A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy, nicknamed the Bullseye, is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes, along with one foreground star at left.

Straight Shot: Hubble Investigates Galaxy with Nine Rings
