Hubble and Web images reveal that the effect of DART was greater than expected: ScienceAlert

The James Webb and Hubble telescopes on Thursday revealed their first images of a spacecraft that deliberately collided with an asteroid, with astronomers noting that the impact appears to be much larger than expected. Global telescopes set their sights on the space rock Demorphos earlier this week to conduct a historic test of Earth’s ability …

NASA and SpaceX are conducting a six-month feasibility study to assess whether a Dragon mission could safely boost the orbit of, and perhaps also otherwise service, the Hubble Space Telescope.

SpaceX, NASA considering Dragon mission to Hubble Space Telescope

Astronauts could visit the Hubble Space Telescope again one day, this time on a private spacecraft. Hubble It launched into Earth orbit in April 1990 and received five groups of visitors over the next two decades. These crews of astronauts, who arrived on NASA’s space shuttle missions, have repeatedly repaired, maintained and upgraded the iconic …

An ‘exceptionally rare’ meteorite impact crater found in the Twin Cities metro

An exceptionally rare meteorite crater was discovered in Inver Grove Heights, Minnesota, and its size indicates that if it had struck today, it would have wiped out a massive portion of the Twin Cities. The crater was discovered several hundred feet underground by researchers from the University of Minnesota Geological Survey (MGS). It is the …

Exploring Ceres in the laboratories

Scientists determine the source of the unexpected geological activity of the planet Ceres

The dwarf planet Ceres is featured in these false-color designs, which highlight differences in surface materials. Images from NASA’s Dawn spacecraft were used to create a movie of Ceres’ orbit, followed by an overhead view of Ocator Crater, home to Ceres’ brightest region. Credit: NASA/JPL Modeling reveals how Ceres is triggering unexpected geological activity. According …

Europe

Consequences of asteroid crashes: Why is Europe sending a probe to DART-hit Demorphos?

ESA’s Hera mission will reach the binary asteroid system Didymos more than four years after NASA’s DART probe collided with one of its two space rocks. By then, all the dust from the experimental collision will have settled, allowing Hera and its accompanying cubes to transform the Didymus duo into the best-explored space rocks in …

Prequel “jaw”? Fishing for fossils of fish from China includes the oldest teeth ever

This illustration provided by Heming Zhang in September depicts some of the fossil fish, more than 400 million years old, found by researchers in southern China, reported in a series of studies published in Nature on Wednesday. Fossils go back to the Silurian period when scientists believe that our ancestors, who were still swimming on …
