APOD: 2024 February 4 Б The Cone Nebula from Hubble
3.02.2024

Stars are forming in the gigantic dust pillar called the Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar nurseries where natal clouds of gas and dust are buffeted by energetic winds from newborn stars. The Cone Nebula, a well-known example, lies within the bright galactic star-forming region NGC 2264.

APOD: 2023 June 30 Б Orbits of Potentially Hazardous Asteroids
29.06.2023

Are asteroids dangerous? Some are, but the likelihood of a dangerous asteroid striking the Earth during any given year is low. Because some past mass extinction events have been linked to asteroid impacts, however, humanity has made it a priority to find and catalog those asteroids that may one day affect life on Earth.

APOD: 2023 September 10 Б An Annular Solar Eclipse over New Mexico
9.09.2023

What is this person doing? In 2012, an annular eclipse of the Sun was visible over a narrow path that crossed the northern Pacific Ocean and several western US states. In an annular solar...

APOD: 2024 July 23 Б The Crab Nebula from Visible to X Ray
22.07.2024

What powers the Crab Nebula? A city-sized magnetized neutron star spinning around 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core.

APOD: 2025 April 14 Б The Galactic Center in Radio from MeerKAT
13.04.2025

What's happening at the center of our galaxy? It's hard to tell with optical telescopes since visible light is blocked by intervening interstellar dust. In other bands of light, though, such as radio, the galactic center can be imaged and shows itself to be quite an interesting and active place.

APOD: 2025 May 4 Б Spin up of a Supermassive Black Hole
3.05.2025

How fast can a black hole spin? If any object made of regular matter spins too fast -- it breaks apart. But a black hole might not be able to break apart -- and its maximum spin rate is really unknown.

APOD: 2023 July 25 Б The Eagle Nebula with Xray Hot Stars
24.07.2023

What do the famous Eagle Nebula star pillars look like in X-ray light? To find out, NASA's orbiting Chandra X-ray Observatory peered in and through these interstellar mountains of star formation.

APOD: 2023 October 23 Б Moon Io from Spacecraft Juno
22.10.2023

There goes another one! Volcanoes on Jupiter's moon Io keep erupting. To investigate, NASA's robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is about...

APOD: 2024 March 18 Б Comet Pons Brooks Swirling Coma
17.03.2024

A bright comet will be visible during next month's total solar eclipse. This very unusual coincidence occurs because Comet 12P/Pons-Brooks's return to the inner Solar System places it by chance only 25 degrees away from the Sun during Earth's April 8 total solar eclipse.

APOD: 2023 October 10 Б Hidden Orion from Webb
9.10.2023

The Great Nebula in Orion has hidden stars. To the unaided eye in visible light, it appears as a small fuzzy patch in the constellation of Orion. But this image was taken by the Webb Space Telescope in a representative-color composite of red and very near infrared light.
