Like Sherlock Holmes’s magnifying glass, the NASA/ESA Hubble Space Telescope can peer into an astronomical mystery in search of clues. The enigma in question concerns the globular cluster Ruprecht 106, pictured here. Unlike most globular clusters, Ruprecht 106 may be what astronomers call a single population globular cluster. While the majority of stars in a...
There is a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun. The results come from a long observation with NASA’s Chandra X-ray Observatory of Abell 2146, a pair of colliding galaxy clusters located about 2.8 billion light years from Earth. Galaxy clusters contain hu...
The International Space Station orbits into a dawn 261 miles above a cloudy Pacific Ocean in this image from April 2022. Not only does the station crew snap beauty shots of the planet we call home, the crew also conducts a variety of Earth and space science, including observations of the world’s oceans. NASA also has a variety of Earth-observing missio...
This November 1996 image from Magellan shows Dickinson, an impact crater in the northeastern Atalanta region of Venus. The image is approximately 115 miles (185 kilometers) wide at the base and 43 miles (69 kilometers) in diameter. The crater is complex, characterized by a partial central ring and a floor flooded by radar-dark and radar-bright materials. Hum...
NASA’s Space Launch System (SLS) rocket with the Orion spacecraft leaves the Vehicle Assembly Building atop a mobile launcher on June 6, 2022, at NASA’s Kennedy Space Center in Florida. At approximately 8:20 a.m. EDT, NASA’s Artemis I Moon rocket arrived at the spaceport’s Launch Complex 39B after an eight-hour journey ahead of the next wet dress rehearsal a...
The Apollo 1 monument at Arlington National Cemetery was dedicated on Thursday, June 2, 2022, in Arlington, Va. The monument honors and memorializes the Apollo 1 crew of Virgil I. “Gus” Grissom, Edward H. White II, and Roger B. Chaffee. Family members of Apollo 1 astronaut Roger B. Chaffee were joined by NASA Administrator Bill Nelson as they placed flowers ...
This image features a spectacular set of rings around a black hole, captured using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings reveal information about dust located in our galaxy, using a similar principle to the X-rays performed in doctor’s offices and airports. The black hole is part ...
Hurricanes are the most powerful weather event on Earth. The 2022 Atlantic hurricane season extends from June 1 to November 30. Faster than a cheetah, the fastest animal on land, hurricanes produce winds of 74 miles an hour (119 kilometers per hour) or more. In this image from 2021, the crew aboard the International Space Station snapped this image of Hurric...
The Moon, with Earth’s shadow draping across it during the May 15, 2022, lunar eclipse, is pictured in between the International Space Station’s Nauka multipurpose laboratory module and the Rassvet module. Attached to Nauka is the new European robotic arm that was continuing checkouts and mobility tests. Image Credit: NASA 在2022年5月15日的月食期间，月球被地球的...
This new image from NASA’s Hubble Space Telescope looks at two spiral galaxies, collectively known as Arp 303. The pair, individually called IC 563 (bottom right) and IC 564 (top left), are 275 million light-years away in the direction of the constellation Sextans. The image holds data from two separate Hubble observations of Arp 303. The first used Hubble’s...
