“The secondary gap we see in the system is a strong indication of the presence of an ice giant in the system,” Gaspar said. The observations from Webb, which launched in 2021 and began collecting data last year, were made by its Mid-Infrared Instrument (MIRI). “Until now, nearly all resolved images of debris disks were […]
For its scientific missions, NASA has tasked industry with developing an unpressurized — that is, open top — rover designed for two people by 2028. Unlike the rovers of the Apollo missions, it would have to operate autonomously even without astronauts on board. This means surviving the cold lunar nights, which can last up to […]
Hakuto means “white rabbit” in Japanese and refers to the Japanese folklore that a white rabbit lives on the moon. The project was one of five finalists in Google’s Lunar X Prize competition to land a rover on the Moon before the 2018 deadline, which passed without a winner. With only 200 employees, ispace has […]
The plan for the integrated test flight was for the Super Heavy booster to separate from the Starship after launch and splashdown in the Gulf of Mexico. They however failed to separate and the booster rocket and Starship spacecraft spun out of control, exploding four minutes into the test flight, in what SpaceX politely called […]
First discovered 400 years ago by astronomer Galileo Galilei, Jupiter’s icy moons were long overlooked as potential candidates to host life. But previous space probes have suggested that beneath their icy shells, there are vast oceans of liquid water – a key ingredient for life as we know it. This has made Ganymede and Europa […]
Stéphane Charlot, a researcher at the Astrophysics Institute of Paris and co-author of the two new studies, told AFP that the most distant galaxy – called JADES-GS-J13-0 – formed 320 million years after the Big Bang. He said that this is the biggest distance observed by astronomers so far. The Webb telescope also confirmed the […]
He told AFP that although it was “very close”, there was nothing to worry about. Smaller asteroids fly by every day, but one of this size comes this close to Earth only about once every 10 years, he said. The asteroid will pass 175,000 kilometers (109,000 mi) from Earth at a speed of 28,000 kilometers […]
Relativity aims to build a rocket that is 95 percent 3D-printed. Terran 1 is propelled by engines using liquid oxygen and liquid natural gas—the “propellant of the future,” capable of eventually fueling travel to Mars, says Relativity. SpaceX’s Starship and Vulcan rockets being developed by United Launch Alliance use the same fuel. Relativity is also […]
Webb’s NIRCam instrument, which operates in near-infrared wavelengths invisible to the naked eye, observed six galaxies in a little-known region of the sky, according to a study published in the journal Nature. The two galaxies had previously been observed by the Hubble Space Telescope, but they were too faint in those images to go unnoticed. […]
Francois Forget, an astrophysicist at France’s CNRS scientific research center, said that “this new impetus for cooperation is linked to the fact that this time the US has a joint project with Europe: Mars sample return.” The mission, planned for around 2030, aims to return to Earth samples collected from Mars by both ExoMars and […]
According to Bialik, the multi-polar and rapidly changing internal structure of the nebula makes it not easy to explain using existing models of how planetary nebulae form and evolve. The star at the center of the nebula, which is hidden by dust and debris, may have merged with a companion star or pulled material from […]
Dark matter, which dominates the halo, makes up the majority of the universe’s mass and is thought to be responsible for its core structure, with its gravity influencing visible matter to come together and form stars and galaxies. The far outer edge of the halo is a poorly understood region of the Milky Way. These […]
Former astronaut Walter Cunningham, who flew into space aboard Apollo 7 in 1968 as part of the first crewed Apollo mission, paved the way for 12 others to land on the moon in later years, NASA said. Died on Tuesday at the age of 90. Cunningham joined crewmates Walter Schirra and Don Eisele for the […]
