Thousands of Black Holes Surround the Heart of our Galaxy

(From NASA’s Image of the Day, June 19, 2020) Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory. This black hole bounty consists of stellar-mass black holes, which typically weigh between five to 30 times the mass of our Sun….

Proposed Trident Mission Could Explore Neptune’s Moon Triton in 2038

(News from NASA) Voyager 2 is the only spacecraft ever to have flown past Neptune, and it left a lot of unanswered questions. The views were as stunning as they were puzzling, revealing massive, dark plumes of icy material spraying out from Triton‘s surface. But how? Images showed that the icy landscape was young and…

ESA’s Trace Gas Orbiter Detects Green Airglow Around Mars

Many photographs taken from low-Earth orbit, especially from the Space Station while on the night side of Earth, show a thin line of green or yellowish light just above the limb of our planet. This is called airglow, and it’s caused by excited oxygen atoms high in the atmosphere releasing energy in the form of…

Solar Orbiter is Now Capturing the Closest-Ever Pictures of the Sun

(News from ESA) On June 15, 2020, the ESA/NASA Solar Orbiter spacecraft made its first close approach to the Sun (perihelion), coming within 77 million kilometers (48 million miles) of its surface—about half the distance between the Sun and Earth. Over the next week mission scientists will test the spacecraft’s ten science instruments, including the six…

New Horizons is Far Enough from Earth to See an “Alien Sky”

(News from JHUAPL) For the first time, a spacecraft has sent back pictures of the sky from so far away that some stars appear to be in different positions than we see from Earth. More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it…

NASA Selects Astrobotic Rover to Prospect for Water on the Moon’s South Pole

  (News from NASA) NASA has awarded Astrobotic of Pittsburgh $199.5 million to deliver NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon’s South Pole in late 2023. VIPER will collect data – including the location and concentration of ice – that will be used to inform the first global water resource maps of the…

Mariner 10’s View of Venus from 1974, Revisited and Remastered

(News from NASA) As it sped away from Venus, NASA’s Mariner 10 spacecraft captured this seemingly peaceful view of a planet the size of Earth, wrapped in a dense, global cloud layer. But, contrary to its serene appearance, the clouded globe of Venus is a world of intense heat, crushing atmospheric pressure and clouds of…

Mars Odyssey Orbiter Takes Moon Phobos’ Temperature

(News from NASA’s Jet Propulsion Laboratory) Three new views of the Martian moon Phobos have been captured by NASA’s Mars Odyssey orbiter. Taken this past winter and this spring, they capture the moon as it drifts into and out of Mars’ shadow. Combined with three previous images, these observations represent waxing, waning and full views…

Titan is Drifting Away from Saturn Much Faster than We Thought

Recent research using data acquired by NASA’s Cassini spacecraft reveals that Titan is moving away from Saturn at a much faster rate than previously thought. How fast? Read on… “This result brings an important new piece of the puzzle for the highly-debated question of the age of the Saturn system and how its moons formed.”…
