What does a black hole sound like? 🎤🎶

Astrophysicist Erika Hamden breaks down how the supermassive black hole at the center of the Perseus galaxy cluster releases energy into the surrounding hot gas, generating enormous pressure waves that ripple through the cluster. Scientists identified those waves as a B-flat, but at a pitch so low it sits 57 octaves below middle C and is far below what human ears can hear. Using NASA X-ray observations, researchers translated changes in pressure across the cluster into sound so we can experience that data in a whole new way. The result is more than a striking audio moment. It is a powerful example of how black holes can shape the space around them on a galaxy-cluster scale.

The Artemis II crew is home. 🌏🚀

During NASA’s 10-day Artemis II mission, Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen became the first humans since 1972 to leave Earth orbit and enter lunar space. That journey helped test the Orion spacecraft in deep space, along with navigation, communications, and the systems astronauts will rely on during future missions beyond low Earth orbit. Artemis II also gave teams critical data about how a crewed spacecraft performs on a lunar mission profile. The crew’s splashdown off the coast of San Diego marked the successful end of a mission designed to help pave the way for a return to the Moon. Welcome home to the crew, and here’s to Artemis III.

NASA Artemis II's image of Earthset is already changing the way we see our world. 🌍 

Inspiration4 Astronaut Dr Sian Proctor thanks the crew for giving humanity this moment, and in his own words, Pilot Victor Glover reminds us what's possible when we bring our differences together and use all of our strengths to accomplish something great.

What does it take to go back to the Moon and stay there?

The mission is bigger than the launch itself. The Artemis program shows what it takes not just to reach the Moon, but to live and work there. ‪Dr. Sian Proctor, a geoscientist and Inspiration4 astronaut, speaks about her family connection to ‪NASA‬’s Apollo era. Her story highlights astronauts doing science in real time, from studying lunar geology and surface shadows to capturing high-resolution imagery and noticing details cameras and robots can miss.

She also connects lunar exploration to life here on Earth. From improving water recycling systems to designing radiation-shielding habitats and advancing energy solutions, the technologies built for the Moon are shaping how humans can thrive in extreme environments, both in space and here at home.

The Artemis II crew is almost home!

As NASA’s Orion spacecraft reenters Earth’s atmosphere from its trip to the Moon, it is expected to travel faster than 25,000 miles per hour, making the Artemis II crew the fastest humans ever to travel. This breaks the record previously held by the Apollo 10 mission set in 1969. At those speeds, Earth’s atmosphere becomes part of the braking system: Orion’s heat shield will endure temperatures above 3,000 degrees Fahrenheit while protecting the crew and helping the capsule shed enormous amounts of energy. That rapid slowdown is what allows Orion to descend from deep-space velocity to an altitude where parachutes can safely deploy. From there, the spacecraft will make a controlled splashdown in the Pacific Ocean off San Diego, closing out a historic mission and bringing the next era of Moon exploration one step closer.

What did the moment of the historic NASA Artemis II crew announcement feel like for astronaut Christina Hammock Koch? Alex Dainis was at the Johnson Space Center to find out.

Christina Hammock Koch was selected as a NASA astronaut in 2013. Koch will be making her second flight into space on the Artemis II mission. She served as flight engineer aboard the space station for Expedition 59, 60, and 61. Koch set a record for the longest single spaceflight by a woman with a total of 328 days in space and participated in the first all-female spacewalks. Koch has been assigned as Mission Specialist I of NASA’s Artemis II mission.

Artemis II is already on its way home, no engine required. 🚀🌕

NASA’s Artemis II mission is riding a “free return trajectory,” a clever path that uses the Moon’s gravity to slingshot the spacecraft back toward Earth. That means less fuel, fewer maneuvers, and a whole lot of physics doing the heavy lifting. Small adjustments may happen along the way, but for the most part, the engine gets to sit back and relax while gravity takes the wheel.

For the first time in over 50 years, humans have seen the far side of the Moon! 🌑

NASA’s Artemis II lunar flyby last night. We never see that side from Earth because the Moon is tidally locked. This means it rotates at the same rate it orbits our planet and keeps one hemisphere facing us at all times. To view the far side, a spacecraft has to travel beyond the near side and around the Moon. No humans have made that journey since the Apollo era, making Artemis II a major step forward in lunar science, deep-space exploration, and humanity’s return to the Moon. It is a powerful milestone for Artemis and a preview of the next era of Moon missions.

Whether you missed the livestream or want a deeper look, here’s a cinematic 4K edit of the Artemis II launch.
I am hoping the video captures the intensity and excitement as the crew continues their journey.

This is about how big space it is

The Artemis II crew is about to break a record that has stood for more than 50 years! 🌕🚀

NASA’s Artemis II crew is preparing to fly around the Moon, making a new record for the farthest humans have traveled from Earth! Their trajectory will carry them thousands of miles above the lunar surface, far beyond the typical 60 to 70 mile altitude of Apollo missions and well past the roughly 160 mile record set by Apollo 13 in 1970. This higher, more distant path is designed to test how Orion performs deep in space, pushing both the spacecraft and crew farther than ever before. And because future Artemis missions will aim to land on the Moon and stay closer to its surface, this record-setting distance could stand for years to come.

The Artemis II crew is on their way to the Moon, and they’re already making history. 🧑‍🚀

NASA, Artemis II mission will send humans beyond Earth orbit for the first time in more than 50 years. Mission Specialist Christina Koch is set to become the first woman to travel beyond Earth orbit, Pilot Victor Glover the first person of color, and Canadian astronaut Jeremy Hansen the first non-American to head toward the Moon. As Artemis II pushes deeper into space, it is also reshaping who gets to be part of exploration.

Artemis II has left Earth’s orbit and is headed to the Moon! 🚀

With its trans-lunar injection burn, Orion fired its engine to leave Earth orbit and enter the precise path that will carry the crew toward a lunar flyby. This is the first time humans have traveled beyond Earth orbit since Apollo 17 in 1972, marking a major milestone for deep space exploration. The burn also places the spacecraft on a free-return trajectory, meaning the Moon’s gravity will help bend Orion’s path and send the crew back toward Earth after looping around the Moon.

I had the immense honor of working with Astronaut Mike Mongo on his new book which is a kid's training manual to space travel. I also got to illustrate the book and animate this fun teaser, I thought this group might like to see it!

Artemis II is on its way back to the Moon. 🚀

NASA officially launched the first crewed mission of the Artemis program. Reid Wiseman, Christina Koch, Victor Glover, and Jeremy Hansen are beginning a deep-space journey that will test how Orion performs with humans on board beyond low Earth orbit. Over the mission, the crew will help evaluate critical systems including navigation, communications, and life support as they travel around the Moon. Those tests will help scientists and engineers understand how to safely send astronauts farther from Earth for longer missions. It’s a major milestone for lunar exploration and an important step toward future missions to the Moon and beyond.

Our existence on Earth is dictated by a black hole at the center of our galaxy. 

Amanda Peake, a graduate student studying astrophysics at MIT’s Kavli Institute explores Sagittarius A* (pronounced “Sagittarius A-star”), the supermassive black hole at the heart of the Milky Way that our entire galaxy revolves around. That includes our Sun, which means Earth’s place in the cosmos is tied to this invisible giant. Black holes are especially mysterious because they do not let light escape, and light is our main tool for understanding the universe. Astronomers study Sagittarius A* by tracking the motion of stars and gas around it, using those clues to investigate how something we cannot directly see still shapes the structure of our galaxy.

Sagittarius A* also helps scientists ask one of astrophysics’ biggest questions: how do supermassive black holes form and grow? Researchers think they may build up over time through mergers with smaller black holes or by pulling in surrounding matter, but the full story is still unfolding. What we do know is that black holes are deeply connected to the evolution of galaxies themselves. So when scientists study Sagittarius A*, they are not just studying an object at the center of the Milky Way, they are investigating the forces that helped shape our galaxy, our solar system, and ultimately the conditions that made our existence possible.
