Carina Cliffs from the Webb Space Telescope
5.09.2022

Stars created these cliffs. Specifically, the destructive winds and energetic light from the stars in the open cluster NGC 3324 eroded away part of a mountain of dark interstellar dust in the northern part of the Carina Nebula.

Jupiter from the Webb Space Telescope
30.08.2022

This new view of Jupiter is illuminating. High-resolution infrared images of Jupiter from the new James Webb Space Telescope (Webb) reveal, for example, previously unknown differences between high-floating bright clouds -- including the Great Red Spot -- and low-lying dark clouds.

Bright Planets at McMath Pierce Solar Telescope
16.03.2012

Bright planets Venus and Jupiter are framed by the National Solar Observatory's McMath-Pierce Solar Telescope in this very astronomical scene. The photo was taken at Kitt Peak National Observatory on March 9.

APOD: 2025 September 13 Б Star Trails over One Mile Radio Telescope
13.09.2025

The steerable 60 foot diameter dish antenna of the One-Mile Telescope at Mullard Radio Astronomy Observatory, Cambridge, UK, is pointing skyward in this evocative night-skyscape. To capture the dramatic scene, consecutive 30 second exposures were recorded over a period of 90 minutes.

An Active Night over the Magellan Telescopes
21.02.2017

The night sky is always changing. Featured here are changes that occurred over a six hour period in late 2014 June behind the dual 6.5-meter Magellan Telescopes at Las Campanas Observatory in Chile.

Tau Herculids Meteors over Kitt Peak Telescopes
1.06.2022

It wasn't the storm of the century -- but it was a night to remember. Last night was the peak of the Tau Herculids meteor shower, a usually modest dribble of occasional meteors originating from the disintegrating Comet 73P/Schwassmann-Wachmann 3.

Webb Telescope Mirror Rises after Assembly
9.05.2016

Move over Hubble -- here comes the James Webb Space Telescope (JWST). JWST promises to be the new most powerful telescope in space. In the last month, the 18-segment gold-plated primary mirror for JWST was unveiled. In the featured time-lapse video taken last week, the 6.5-meter diameter mirror was raised to a vertical position.

HESS Gamma Ray Telescope
6.09.2002

Most ground-based telescopes with lenses and mirrors are hindered by the Earth's nurturing, protective atmosphere that blurs images and scatters and absorbs light. But this telescope was designed to detect extreme gamma rays - photons with over 100 billion times the energy of visible light - and actually requires the atmosphere to operate.

Hubble Telescope Maps Pluto
11.03.1996

No spacecraft from Earth has yet explored Pluto but astronomers have found ways of mapping its surface. A stunning map of this distant, diminutive planet, the first based on direct images, was revealed late last week in a Hubble Space Telescope press release.

Comet Holmes from the Hubble Space Telescope
28.11.2007

Why did Comet Holmes brighten? The unexpectedly bright Comet 17P/Holmes continues to grace northern skies as a naked-eye addition to the constellation Perseus. Any northern sky enthusiast with a dark sky, a bright curiosity, and a recent sky map should still be able to locate the comet in a few minutes.
