How NASA Science Data Defends Earth from Asteroids
Sunday, 13 April 2025 08:11
The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA's Center for Near Earth Object Studies (CNEOS) at the agency's Jet Propulsion Laboratory in Southern California. The probability of collision peaked at over 3% on Feb. 18 - the highest ever recorded for an object of its size. This sparked c Astronomers identify rare Earth-crossing asteroid from unexpected source

Astronomers at W. M. Keck Observatory on Maunakea, Hawai'i, have traced the origin of 2024 YR4, an Earth-crossing asteroid discovered in December 2024, to a surprising location. Contrary to expectations, the solid, stony asteroid appears to have emerged from a central Main Belt asteroid family between Mars and Jupiter-a region not previously associated with Earth-crossing bodies.

Earth planning date: Wednesday, April 9, 2025: Our drive from Monday's plan was mostly successful, putting us ~22 meters down the "road" out of an expected 30 meters. A steering command halted the drive a little short when we tried to turn-in-place but instead turned into a rock, which also had the effect of making our position too unstable for arm activities.

ESA's XMM-Newton telescope has become instrumental in monitoring an extraordinary cosmic awakening: a massive black hole in a galaxy 300 million light-years away has transitioned from complete dormancy to producing the most powerful and extended X-ray eruptions ever observed.
The black hole lies in SDSS1335+0728, an otherwise unremarkable galaxy in Virgo. After decades of inactivity, it be SwRI links solar jet to unprecedented helium-3 surge
Sunday, 13 April 2025 08:11
The Solar Orbiter mission, a collaboration between NASA and ESA, has detected the most intense concentration of the rare helium-3 (3He) isotope ever recorded from the Sun, sparking new interest in the origin of solar energetic particles (SEPs). Scientists led by Southwest Research Institute (SwRI) have now traced the source of this extraordinary event to a diminutive solar jet on the Sun's surfa Research reveals tidal forces disrupting nearby dwarf galaxy
Sunday, 13 April 2025 08:11
New research led by Satoya Nakano and Kengo Tachihara at Nagoya University has uncovered compelling evidence that the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing tidal disruption due to gravitational forces from its larger companion, the Large Magellanic Cloud (LMC). Published in The Astrophysical Journal Supplement Series, the findings offer ne Do "completely dark" dark matter halos exist?
Sunday, 13 April 2025 08:11
Every galaxy is thought to form at the center of a dark matter halo - a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't yet know whether star-free dark matter halos exist.

Asteroid risk reevaluated with fresh data from Earth and space
Friday, 11 April 2025 08:38
An international coalition of scientists is closely monitoring near-Earth asteroid 2024 YR4, with new calculations showing a dramatic reduction in its potential to strike Earth in 2032. Initially estimated at a 3 percent probability, the chance of an Earth impact has now been downgraded to less than 0.001 percent.
Discovered in December 2024, 2024 YR4 prompted the International Asteroid Wa
