Dubai floods seen from space Hubble goes hunting for small main-belt asteroids
Write a comment
Astronomers recently used a trove of archived images taken by the NASA/ESA Hubble Space Telescope to visually snag a largely unseen population of smaller asteroids in their tracks. The treasure hunt required pursuing 37 000 Hubble images spanning 19 years. The payoff was finding 1701 asteroid trails, with 1031 of those asteroids uncatalogued. About 400 of these uncatalogued asteroids are about below a km in size.
NASA chief warns of Chinese military presence in space
Write a comment
China is bolstering its space capabilities and is using its civilian program to mask its military objectives, the head of the US space agency NASA said Wednesday, warning that Washington must remain vigilant.
"China has made extraordinary strides especially in the last 10 years, but they are very, very secretive," NASA administrator Bill Nelson told lawmakers on Capitol Hill.
"We believe that a lot of their so-called civilian space program is a military program. And I think, in effect, we are in a race," Nelson added.
He said he hoped Beijing would "come to its senses and understand that civilian space is for peaceful uses," but added, "We have not seen that demonstrated by China."
Nelson's comment came as he testified before the House appropriations committee on NASA's budget for fiscal 2025.
He said the United States should land on the moon again before China does, as both nations pursue lunar missions, but he expressed concern that were Beijing to arrive first, it could say, "'Okay, this is our territory, you stay out.'"
The United States is planning to put astronauts back on the moon in 2026 with its Artemis 3 mission.

Orbital changes suggest recent formation of underground ocean on Saturn's Mimas
Write a comment
Recent studies suggest that Mimas, one of Saturn's moons, has developed a substantial underground ocean due to a decrease in its orbital eccentricity, leading to the melting and thinning of its icy exterior.
"Previously, we established that Mimas could currently host an ocean world only if it previously had a thicker icy shell. However, the process transitioning from thick to thinner ice w Tyvak International's Centauri-6 satellite enters operational orbit

Write a comment
Did you know the Sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mission, blossoms around the center of a sunspot group, where magnetic conditions are strong. It straddles two atmospheric layers known as the chromos
