Copyright: NASA/Bill Ingalls; Text: Ogetay Kayali (MTU) We are one small step closer to returning to the Moon. A new chapter in human exploration began yesterday when NASA’s Artemis II launched aboard the Space Launch System (SLS) from Kennedy Space Center. Carrying four astronauts, the Orion spacecraft’s planned lunar flyby will be the first in […]

Copyright: Richard Whitehead Text: Keighley Rockcliffe (NASA GSFC, UMBC CSST, CRESST II) What unexpected things do you see when you look up at the night sky? Today’s image resembles an abstract painting, with large swaths of color strewn across a cosmic canvas seemingly without design. Despite the image’s abstract nature, the human mind finds patterns, […]

Titania’s tortured terrain is a mix of canyons, cliffs, and craters. NASA’s interplanetary robot spacecraft Voyager 2 passed the largest moon of Uranus in 1986 and took the feature picture. That the trenches of Titania resemble those on another moon of Uranus, Ariel, indicate that Titania underwent some violent surface event possibly related to water […]

Dramatic dust lanes run across the center of unusual elliptical galaxy Centaurus A. These dust lanes are so thick they almost completely obscure the galaxy’s center […]

What are these Earthlings trying to tell us? The featured message was broadcast from Earth towards the globular star cluster M13 in 1974. During the dedication of an upgrade to the Arecibo Observatory – then the largest single radio telescope in the world – a string of 1’s and 0’s representing the diagram was sent. […]

Robert H. Goddard, considered the father of modern rocketry, was born in Worcester Massachusetts in 1882. As a 16 year old, Goddard read H.G. Wells’ science fiction classic “War Of The Worlds” and dreamed of space flight. By 1926 he had designed, built, and flown the world’s first liquid fuel rocket. Launched 100 years ago, […]

Copyright: Peter Kennett Scanning the skies for galaxies, Canadian astronomer Paul Hickson and colleagues identified some 100 compact groups of galaxies, now appropriately called Hickson Compact Groups. The four prominent galaxies seen in this intriguing telescopic skyscape are one such group, Hickson 44. The Hickson 44 galaxy group is about 100 million light-years distant, far […]

What is the sound of two black holes merging in deep space? Sound waves don’t propagate in vacuum, but gravitational waves do. In 2015 we were able to “hear” them for the first time and confirm one of Albert Einstein’s theoretical predictions. Each square on the grid of the featured image represents one of the […]
