Hubble Spies Stellar Blast Setting Clouds Ablaze
This new NASA Hubble Space Telescope image captures a jet of gas from a forming star shooting across the dark expanse. The bright pink and green patches running diagonally through the image are HH 80/81, a pair of Herbig-Haro (HH) objects previously observed by Hubble in 1995. The patch to the upper left is part of HH 81, and the bottom streak is part of HH 80.
Herbig-Haro objects are bright, glowing regions that occur when jets of ionized gas ejected by a newly forming star collide with slower, previously ejected outflows of gas from that star. HH 80/81’s outflow stretches over 32 light-years, making it the largest protostellar outflow known.
Protostars are fed by infalling gas from the surrounding environment, some of which can be seen in residual “accretion disks” orbiting the forming star. Ionized material within these disks can interact with the protostars’ strong magnetic fields, which channel some of the particles toward the pole and outward in the form of jets.
As the jets eject material at high speeds, they can produce strong shock waves when the particles collide with previously ejected gas. These shocks heat the clouds of gas and excite the atoms, causing them to glow in what we see as HH objects.
HH 80/81 are the brightest HH objects known to exist. The source powering these luminous objects is the protostar IRAS 18162-2048. It’s roughly 20 times the mass of the Sun, and it’s the most massive protostar in the entire L291 molecular cloud. From Hubble data, astronomers measured the speed of parts of HH 80/81 to be over 1,000 km/s, the fastest recorded outflow in both radio and visual wavelengths from a young stellar object. Unusually, this is the only HH jet found that is driven by a young, very massive star, rather than a type of young, low-mass star.
The sensitivity and resolution of Hubble’s Wide Field Camera 3 was critical to astronomers, allowing them to study fine details, movements, and structural changes of these objects. The HH 80/81 pair lies 5,500 light-years away within the Sagittarius constellation.

Hubble’s Album of Planet-Forming Disks Hubble images of protoplanetary disks in visible and infrared light show dusty regions around newly developing stars where planets may form.Left: NASA, ESA, and K.

This collection of new images taken by NASA’s Hubble Space Telescope showcases protoplanetary disks, the swirling masses of gas and dust that surround forming stars, in both visible and infrared wavelengths. Through observations of young stellar objects like these, Hubble helps scientists better understand how stars form.
Jets of gas blast from protostars in these visible-light images. HH 390’s outflow is accompanied by a one-sided nebula, evidence that the protoplanetary disk is not viewed edge-on from our perspective. Tau 042021 is a large, symmetrical disk seen edge-on, and is in a late stage of dust evolution, since the dust particles have clumped together into larger grains. HH 48 is a binary protostar system in which gravitational tidal forces from the larger star appear to be influencing the disk of the secondary object. ESO Hα574 is a very compact disk with a “collimated” ― or beam-like and linear ― outflow, and one of the faintest edge-on disks yet recognized.NASA, ESA, and K. Stapelfeldt (Jet Propulsion Laboratory); Processing: Gladys Kober (NASA/Catholic University of America) Download this image (34.6 MB)These visible-light images depict dark, planet-forming dust disks around a hidden, newly developing star, called a protostar. Bipolar jets of fast-moving gases, traveling at about 93 miles (150 km) per second, shoot from both ends of the protostar. The top two images are of protostars found about 450 light-years away in the Taurus Molecular Cloud, while the bottom two are almost 500 light-years away in the Chameleon I star-forming region.
Stars form out of collapsing clouds of gas and dust. As surrounding gas and dust falls toward the protostar, some of it forms a rotating disk around the star that continues to feed the growing object. Planets form from the remaining gas and dust orbiting the star. The bright yellow regions above and below the spinning disks are reflection nebulae, gas and dust lit up by the light of the star.
The jets that are released from the magnetic poles of the stars are an important part of their formation process. The jets, channeled by the protostar’s powerful magnetic fields, disperse angular momentum, which is due to rotational movement of the object. This allows the protostar to spin slowly enough for material to collect. In the images, some of the jets appear to broaden. This occurs when the fast jet collides with the surrounding gas and causes it to glow, an effect called a shock emission.
Bright central protostars and the shadows of their dusty disks appear in these infrared images.NASA, ESA, and T. Megeath (University of Toledo); Processing: Gladys Kober (NASA/Catholic University of America) Download this image (36.6 MB)These edge-on views of protostars in infrared light also reveal thick, dusty protoplanetary disks. The dark areas may look like very large disks, but they are actually much wider shadows cast in the surrounding envelope by the central disks. The bright haze throughout the image comes from light scattering off of the surrounding cloud’s dust grains. The top right and bottom left stars reside in the Orion Molecular Cloud complex about 1,300 light-years away, and the top left and bottom right stars lie in the Perseus Molecular Cloud roughly 1,500 light-years away.
In its early stages, these disks draw from the dust that remains around the forming stars. Unlike visible light, infrared light can travel through this “protostellar envelope.” The protostars in the visible images above are further along in their evolution, so much of the dusty envelope has dissipated. Otherwise, they could not be seen in visible wavelengths.
Viewed in infrared light, the central star is visible through the thick dust of the protoplanetary disks. Bipolar jets are also present but not visible because the hot gas emission isn’t strong enough for Hubble to detect.
HOPS 150 in the top right is actually in a binary system, in orbit with another young protostar. HOPS 150’s companion, HOPS 153, is not pictured in this image.
From a wider Hubble survey of Orion protostars, including HOPS 150 and HOPS 367, astronomers found that regions with a higher density of stars tend to have more companion stars. They also found a similar number of companions between main-sequence (active, hydrogen-fusing stars) and their younger counterparts.

Astronauts Return to Earth in First ISS Medical Evacuation
On Thursday NASA chief Jared Isaacman said the experience of the returned Crew-11 will be used to prepare for future human spaceflight—including to the moon
Unmasking the Sun’s Hidden Gamma Ray Factory
Scientists have finally identified where some of the most powerful radiation bursts from solar flares originate, solving a mystery that has puzzled solar physicists for decades. Researchers at the New Jersey Institute of Technology traced intense gamma rays back to a previously unknown population of particles supercharged to millions of electron volts in the Sun’s atmosphere, revealing the mechanism behind these strange signals.
NASA’s SpaceX Crew-11 Mission Returns, Splashes Down off California
NASA’s SpaceX Crew-11 mission safely splashed down early Thursday morning in the Pacific Ocean off the coast of San Diego, concluding a more than five-month mission aboard the International Space Station.
NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov returned to Earth at 12:41 a.m. PST. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew shortly after landing.
“I couldn’t be prouder of our astronauts and the teams on the ground at NASA, SpaceX, and across our international partnerships,” said NASA Administrator Jared Isaacman. “Their professionalism and focus kept the mission on track, even with an adjusted timeline. Crew-11 completed more than 140 science experiments that advance human exploration. Missions like Crew-11 demonstrate the capability inherent in America’s space program—our ability to bring astronauts home as needed, launch new crews quickly, and continue pushing forward on human spaceflight as we prepare for our historic Artemis II mission, from low Earth orbit to the Moon and ultimately Mars.”
Crew-11 returned home about a month earlier than planned because of a medical concern teams are monitoring with one of the crew members, who remains stable. Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. Prior to return, NASA previously coordinated for all four crew members to be transported to a local hospital for additional evaluation, taking advantage of medical resources on Earth to provide the best care possible.
Following the planned overnight hospital stay, the crew members will return to NASA’s Johnson Space Center in Houston and undergo standard postflight reconditioning and evaluations.
The Crew-11 mission lifted off at 11:43 a.m. EDT on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 15 hours later, the crew’s SpaceX Dragon spacecraft docked to the orbital outpost at 1:27 a.m. CDT on Aug. 2.
During their 167-day mission, the four crew members traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space.
Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.
NASA’s Commercial Crew Program provides reliable access to space, maximizing the use of the International Space Station for research and development by partnering with private U.S. companies, including SpaceX, to transport astronauts to and from the space station.

Sentinel-2 explores night vision
After more than 10 years in orbit, the first Copernicus Sentinel-2 satellite, Sentinel-2A, is still finding new ways to contribute to Earth observation. With its younger siblings, Sentinel-2B and Sentinel-2C, now leading the mission’s core task of delivering high-resolution, ‘camera-like’ images of Earth’s surface, the European Space Agency is pushing Sentinel-2A beyond its original remit.
In recent trials, this elderly satellite was even switched on at night to see how it would perform in the dark – and the results have been strikingly positive, offering encouraging news for the follow-on Copernicus Sentinel-2 Next Generation mission, currently in development.
