Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a study using NASA’s Chandra X-ray Observatory.X-ray: NASA/CXC/Penn State Univ/K.

These images, released on April 14, 2026, show two open star clusters, Trumpler 3 (left) and NGC 2353 (right). They represent a recent study from NASA’s Chandra X-ray Observatory that shows how young Sun-like stars are dimmer in X-rays than previously thought.

This latest study looked at eight clusters of stars between the ages of 45 million and 750 million years old. The researchers found that Sun-like stars in these clusters unleashed only about a quarter to a third of the X-rays they expected. This quieting of young stars is a benefit for the prospects for life on orbiting planets around these stars — not a threat.

One of the most dramatic and memorable scenes from Interstellar comes from Miller’s planet - and if you don’t want a spoiler for an 11 year old movie, feel free to skip to the next paragraph. When the crew arrives on this potential new home for humanity, they are faced with a literal 1.2 km high wall of water bearing down on them quickly. It’s a great representation of how waves on other planets can act differently than on Earth. Admittedly, according to Kip Thorne, the scientific advisor for that movie, those waves are actually caused by the planet’s proximity to a local black hole rather than the wind that forms our waves here.

After an intense few weeks the crew took time to celebrate together with a shared meal proposed by ESA astronaut Sophie Adenot.

It’s a long‑standing tradition: each ESA astronaut works with a chef to create a few special dishes reserved for rare occasions — known as “bonus food”. Sophie’s bonus food was created by multi‑Michelin‑starred chef Anne‑Sophie Pic, offering the crew a taste of French gastronomy far from Earth.

Bonus food, tailored to specific crew members, makes up around one tenth of an astronaut’s menu. Astronauts say it adds variety to their meals, supports mental well‑being, and helps strengthen bonds among the crew in orbit.

One side is scorched to over 200 degrees, while the other is plunged into a darkness so cold it falls below minus 200.

The James Webb Space Telescope has been watching, and what it found tells us something profound about where life might, and might not exist in our Galaxy.

At the heart of our Galaxy lurks a supermassive black hole four million times the mass of our Sun. For decades, astronomers have watched mysterious gas clouds drifting towards it on almost identical paths, wondering where they came from and why. Now, a team of researchers think they have finally cracked the puzzle and the answer involves two massive stars locked in a violent embrace!

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape. But some are completely destroyed in pair-instability supernova explosions. This can explain the so-named "Forbidden Gap" in black hole masses.

NASA’s Boeing 777 has returned to the agency’s fleet after undergoing heavy structural modifications as it transforms from a giant passenger plane into the agency’s next-generation airborne science laboratory. After a check flight and a three-hour transit from Waco, the aircraft returned to NASA’s Langley Research Center in Hampton, Virginia, on April 22.

Since January 2025, the aircraft has been in Texas receiving hardware and structural upgrades to prepare for science operations. The modifications include installing dedicated research stations and extensive wiring. This allows payload systems to communicate with sensors such as lidar and infrared imaging spectrometers during flights. Cabin windows were enlarged and open portals installed at the bottom of the fuselage to mount remote-sensing instruments.

Widened windows along the NASA 777 will serve as viewports for a variety of scientific instrument sensors. Modifications on the belly of the aircraft at the L3Harris facility in Waco require extensive support to ensure aircraft alignment during reassembly. Credit: L3Harris

“Airborne missions at NASA use cutting-edge instruments to explore and understand our home planet,” said Derek Rutovic, program manager for the Airborne Science Program at NASA Headquarters in Washington. “The 777 will be the largest airborne research laboratory in our fleet, collecting data to improve life on our home planet and extend our knowledge of the Earth system as a whole.”

Acquired in 2022 to succeed NASA’s retired DC-8 aircraft, the 777 will expand the agency’s airborne research capacity. It can accommodate 50 to 100 operators and carry 75,000 pounds of equipment for flights lasting up to 18 hours.

“NASA’s DC-8 was an incredible workhorse for Earth science for nearly 40 years,” said Kirsten Boogaard, the NASA 777 program manager at NASA Langley and former deputy program manager of NASA’s DC-8. “Being part of that team, I got to see the impact up close. I’m excited for what the 777 will bring. It gives us the ability to bring together more partners, more educational opportunities, and more instruments. That will make a real difference in the data we collect moving forward.”

The aircraft’s inaugural science mission, slated to deploy in January 2027, will investigate high-impact winter weather events, such as severe cold air outbreaks, wind, snow and ice storms, and hazardous seas. Known as the North American Upstream Feature-Resolving and Tropopause Uncertainty Reconnaissance Experiment (NURTURE), the mission will collect detailed atmospheric observations across a vast region spanning North America, Europe, Greenland, and the Arctic and North Atlantic Oceans.

“We’ve been completing the engineering design and analysis to install the NURTURE payload into the aircraft in parallel with the portal modification,” Rutovic said. “We’re excited to get the airplane back home to NASA and on the road to its first mission.”

The NASA 777’s major structural modification was performed by L3Harris Technologies in partnership with Yulista Holding, LLC. Research station and wiring upgrades in the cabin are being performed by NASA and HII. NASA’s Airborne Science Program is responsible for providing aircraft systems that further science and advance the use of satellite data and is part of the Science Mission Directorate’s Earth Science Division.
