The DART mission made history this week when it was Successfully hit an asteroid – And we were able to see it happen live, from millions of miles away.

As NASA’s twin asteroid redirection test spacecraft approached its target on Monday, images returned to Earth at a rate of one per second of the asteroid Demorphos, which orbits a larger space rock called Didymus.

Each image proved to be better than the previous one, and in the seconds before the DART effect with Dimorphos, the surface of the young moon filled the entire frame.

Demorphos, never seen before, turned egg-shaped and covered in rocks. The rocky asteroid has surprised scientists, who are eager to study images taken by DART before it crashed into the flames of glory.

The researchers estimate that it will take about two months to determine if DART has successfully altered the motion of Dimorphos in space in humanity’s first test of asteroid deflection technology.

The The spacecraft may have taken an amazing first look at an asteroidBut it’s not the only view of an asteroid system we’ve been lucky enough to see.

All eyes were on Didymus and Demorphos for a glimpse into the impact of DART and its consequences, and the early images did not disappoint.

The Hubble Space Telescope and the James Webb Space Telescope observed the collision and Spy columns from material emitted from the surface of Dimorphos.

Ground-based observatories also shared how bright the asteroid system was after it was attacked by DART.

but the The most dramatic photos were the first photos shared by LICIACube, the small Italian satellite that followed DART and watched the entire event from a safe distance. The best part? We’ll see more over the next couple of months.

The Nobel Committee will soon announce the winners of its annual awards next week.

It is difficult to predict who will win these prestigious awards because the candidates, shortlisting and selection process are kept out of public view.

In 2021, none of the Nobel laureates for science were women, which some critics have suggested is more evidence of systematic bias in scientific fields.

But there are plenty of worthy female candidates, such as Dr. Marie Claire King, who discovered cancer-causing genes, and Dr. Marilyn Hughes Gaston, whose work has served as a pathway in the treatment of sickle cell disease.

These icebergs were born from the end of the LeConte glacier in Alaska.

The explosion of fireworks, sizzling bacon, and extended booms of thunder are just some of the sounds associated with the Earth’s massive glaciers cracking and shrinking.

Scientists Set the surprisingly bustling nature of glaciers To find out how quickly ice is melting in the midst of the climate crisis – and reveal the mysteries of the depths.

Glacial ice can be very fizzy, hissing as it releases compressed air and bubbles that have been frozen for hundreds or even thousands of years.

The place where glaciers meet the ocean can be a dangerous place for humans. Observing the acoustics of these dense bodies of ice from afar is changing how researchers understand them and what we know about how their sounds affect animals living in these disappearing habitats.

More than 100 years after the SS Mesaba sank, scientists have found its wreck at the bottom of the Irish Sea.

On April 14, 1912, the British merchant steamer sent a message to the RMS Titanic, but the iceberg’s warning never reached the huge ocean line’s main control center on that fateful night.

Mesaba was torpedoed by a German submarine just six years later, killing 20 people. But the exact location of the ship is not yet known.

Researchers used sonar scanning to find Mesaba – Along with many other shipwrecks It is scattered across 7,500 square miles (19,425 km).

The Webb Telescope has spotted spiral galaxy IC 5332, located 29 million light-years away.

Galaxies far and wide appear to present a shimmering display of the James Webb Space Telescope.

Stunning spiral galaxy ‘bones’ web spotted It is located 29 million light-years from Earth, an even more surprising feat when compared to a Hubble view of the same galaxy.

Meanwhile, astronomers have analyzed Webb’s first image and determined that it contains some of the oldest stars and galaxies in the universe – including one that closely resembles a celestial firework.
