Artemis II detects helium leak but proceeds to safe reentry

NASA's Artemis II mission, the first crewed flight of the Orion spacecraft around the Moon since 1972, has encountered a helium leak in its service module but officials say it poses no threat to the crew's return. The spacecraft, carrying astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, launched on April 1 and is set for splashdown in the Pacific Ocean on Friday evening. Ground teams adjusted the flight plan to study the leak while maintaining nominal performance.

Interstellar comet 3I/ATLAS contains unusual heavy water

A comet from beyond our solar system shows dramatically higher levels of deuterium-rich water than any object seen locally. The findings suggest it formed under much colder conditions than those in our own planetary neighborhood. Researchers used observations from two major telescopes to make the measurements.

Scientists propose detecting alien life via planetary patterns

A team of researchers has introduced a new method to detect extraterrestrial life by identifying statistical patterns across multiple planets rather than focusing on individual worlds. Led by Harrison B. Smith and Lana Sinapayen, the approach relies on life's potential to spread between planets and alter their environments. This 'agnostic biosignature' could help prioritize observations amid limited telescope time.

Black hole in galaxy J1007+3540 erupts after 100 million years

Astronomers have observed a supermassive black hole in galaxy J1007+3540 restarting powerful jets after nearly 100 million years of inactivity. The jets, distorted by intense pressure from a surrounding galaxy cluster, stretch nearly a million light-years. The findings reveal cycles of black hole activity shaping the galaxy's structure.

Meteor impacts may have sparked life on early Earth

Scientists suggest that asteroid impacts created hot, chemical-rich environments that could have kick-started life on Earth. A new review led by recent Rutgers graduate Shea Cinquemani highlights impact-generated hydrothermal systems as potential cradles for life's building blocks. These systems may have persisted for thousands of years, providing ideal conditions for early biology.

Artemis II mission progresses smoothly toward lunar flyby

NASA's Artemis II crew, aboard the Orion spacecraft named Integrity, has successfully departed Earth's orbit and is heading toward the Moon after a key engine burn. The astronauts reported no major issues, shared stunning photos of Earth, and spoke with family and media. The mission remains on track for a closest approach to the Moon on Monday and splashdown on April 10.
