Odysseus and The Dish
1.03.2024

Murriyang, the CSIROБs Parkes radio telescope points toward a nearly Full Moon in this image from New South Wales, Australia, planet Earth. Bathed in moonlight, the 64 meter dish is receiving weak radio signals from Odysseus, following the robotic lander's February 22 touch down some 300 kilometers north of the Moon's south pole.

A Radar Image of Planet Earth
24.08.1995

This image of Mt. Rainier, Washington USA, planet Earth, was produced by the Spaceborne Radar Laboratory which flew on the Space Shuttle Endeavour in 1994. Radar, short for RAdio Detection And Ranging...

Supernova Remnant CTA 1
23.08.2024

There is a quiet pulsar at the heart of CTA 1. The supernova remnant was discovered as a source of emission at radio wavelengths by astronomers in 1960 and since identified as the result of the death explosion of a massive star.

Supernova Remnant In M82
16.12.1999

This false-color radio wavelength picture of an expanding stellar debris cloud is the product of one of the largest radio astronomy experiments ever. Combining the output of 20 radio telescopes scattered around planet Earth...

The Arms of NGC 4258
11.04.2007

Better known as M106, bright spiral galaxy NGC 4258 is about 30 thousand light years across and 21 million light years away toward the northern constellation Canes Venatici. The yellow and red hues in this composite image show the galaxy's sweeping spiral arms as seen in visible and infrared light.

Arecibo: The Largest Telescope
9.03.1996

The Arecibo radio telescope is currently the largest single-dish telescope in the world. First opening in 1963, this 305 meter (1000 foot) radio telescope resides in a natural valley of Puerto Rico. The Arecibo...

An Extreme Black Hole Outburst
11.03.2020

Astronomers believe they have now found the most powerful example of a black hole outburst yet seen in our Universe. The composite, false-color featured image is of a cluster of galaxies in the constellation of Ophiuchus, the serpent-bearer.

The Very Large Array at Moonset
9.10.2020

An inspirational sight, these giant dish antennas of the Karl G. Jansky Very Large Array (VLA) rise above the New Mexico desert at moonset. Mounted on piers but transportable on railroad tracks to change...

Jets from Unusual Galaxy Centaurus A
31.05.2011

Jets of streaming plasma expelled by the central black hole of a massive spiral galaxy light up this composite image of Centaurus A. The jets emanating from Cen A are over a million light years long. Exactly how the central black hole expels infalling matter is still unknown.

The Energetic Jet from Centaurus A
1.05.2003

The center of well-studied active galaxy Centaurus A is hidden from the view of optical telescopes by a cosmic jumble of stars, gas, and dust. But both radio and x-ray telescopes can trace the remarkable jet of high-energy particles streaming from the galaxy's core.
