Astronomy

This image combines a depiction of the sun's magnetic fields with a photograph taken by NASA's Solar Dynamics Observatory. The intricate pattern of lines reveals how the sun's magnetism shifts and adapts in response to its constant internal and surface movements.

Astronomers Unveil New Earth-Sized Exoplanet Orbiting Ultra-Cool Dwarf Star

A 3D rendered image of the spiral galaxy NGC 4151, with a bright central region representing the active galactic nucleus. The image zooms in to show a glowing accretion disk surrounding a supermassive black hole, with twin jets of particles emanating from the disk's center. Colorful spectral lines are overlaid on the image, highlighting the iron fingerprints detected by XRISM's Resolve instrument.

Astronomers’ Simulations Bolster Case for Dark Matter’s Existence

Artist's impression of a magnetar. Magnetars are the cosmic objects with the strongest magnetic fields ever measured in the Universe.

Rare Magnetar Flare Spotted in Nearby Galaxy M82

Galaxy NGC 4383 evolving strangely. Gas is flowing from its core at a rate of over 200 km/s. This mysterious gas eruption has a unique cause: star formation.

Gaia Mission Discovers Monstrous Black Hole in the Milky Way

Artist's visualization of GRB 221009A showing the narrow relativistic jets — emerging from a central black hole — that gave rise to the GRB and the expanding remains of the original star ejected via the supernova explosion. Using the James Webb Space Telescope, Northwestern University postdoctoral fellow Peter Blanchard and his team detected the supernova for the first time, confirming GRB 221009A was the result of the collapse of a massive star. The study’s co-authors also found that the event occurred in a dense star forming region of its host galaxy as depicted by the background nebula.

The attached image shows the sky goddess Nut, covered in stars, is held aloft by her father, Shu, and is arched over Geb, her brother the Earth god. On the left, the rising sun (the falcon-headed god Re) sails up Nut’s legs. On the right, the setting sun sails down her arms towards the outstretched arms of Osiris, who will regenerate the sun in the netherworld during the night.

Unlocking the Secrets of the Universe: DESI’s Groundbreaking 3D Map Reveals Dark Energy Mysteries

This illustration shows the orbits of stars very close to Sagittarius A*, a supermassive black hole at the heart of the Milky Way.

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon emission, which traces the shape of the galactic wind. In the Hubble image, light at .814 microns is colored red, .658 microns is red-orange, .555 microns is green, and .435 microns is blue (filters F814W, F658N, F555W, and F435W, respectively). In the Webb image, light at 3.35 microns is colored red, 2.50 microns is green, and 1.64 microns is blue (filters F335M, F250M, and F164N, respectively). NASA, ESA, CSA, STScI, A.
