It's hard to miss a flashlight beam pointed straight at you. But that beam viewed from the side appears significantly dimmer. The same holds true for some cosmic objects: Like a flashlight, they radiate primarily in one direction, and they look dramatically different depending on whether the beam points away from Earth (and nearby space telescopes) or straight at it. New data from NASA's N

Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study. A better understanding of seismic activity could reveal what's under the moon's icy crust and provide clues to the habitability of its ocean. Enceladus is about 500 kilometers in diameter and almost entirely covered in

Planets which are tilted on their axis, like Earth, are more capable of evolving complex life. This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research is presented at the Goldschmidt Geochemistry Conference. Since the first discovery of exoplanets (planets orbiting distant stars) in 1992, scientists have been looking for worlds wh

A research team co-led by UCL (University College London) has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes. The X-rays are part of Jupiter's aurora - bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but

NASA and Northrop Grumman of Dulles, Virginia, have finalized a contract to develop the Habitation and Logistics Outpost (HALO) for Gateway, which will be a critical way station and outpost in orbit around the Moon as part of NASA's Artemis program. NASA and its commercial and international partners are building Gateway to support science investigations and enable surface landings at the Moon, w

Scientists know that the Earth was bombarded by huge impactors in distant time, but a new analysis suggest that the number of these impacts may have been x10 higher than previously thought. This translates into a barrage of collisions, similar in scale to that of the asteroid strike which wiped out the dinosaurs, on average every 15 million years between 2.5 and 3.5 billion years ago. Some

Today, Mars is a planet of extremes - it's bitterly cold, has high radiation, and is bone-dry. But billions of years ago, Mars was home to lake systems that could have sustained microbial life. As the planet's climate changed, one such lake - in Mars' Gale Crater - slowly dried out. Scientists have new evidence that super salty water, or brines, seeped deep through the cracks, between grains of

It has been a week of heightened apprehension on the Mars Helicopter team as we prepared a major flight challenge for Ingenuity. We uplinked instructions for the flight, which occurred Monday, July 5 at 2:03 am PT, and waited nervously for results to arrive from Mars later that morning. The mood in the ground control room was jubilant when we learned that Ingenuity was alive and well after compl

In 1962 when America was going to the Moon, NASA established Kennedy Space Center in Florida as its Launch Operations Center. This month, the modernized multi-user spaceport marks its 59th anniversary while working to send Americans back to the Moon, helping grow the commercial space industry, and performing research that benefits humanity. The launch of NASA's Artemis I mission - slated t

The 3.9 million pound grant from the UK Space Agency will support the development of Reaction Engines' ground-breaking SABRE technology, enabling low-carbon air-breathing space access propulsion technology to be applied more widely in the space sector and beyond. Science Minister Amanda Solloway and Transport Minister Rachel Maclean visited Reaction Engines at its site in Culham, Oxfordshi
