The Smallest, Lightest Neutron Star Ever Seen Could be a “Strange Star”

The life of every star is a fight against gravity. Stars are so massive they risk collapsing under their own weight, but this is balanced by the heat and pressure a star generates through nuclear fusion. Eventually, that comes to an end. The outer layers of a star will be cast off, and the remaining core will become a stellar remnant. Which kind of remnant depends on the mass of the core.

Private space mission to study how solar flares kill exoplanet life

A private space mission will study how solar flares generated by nearby stars can affect habitability of exoplanets in their orbit.

ESA plans for low-orbiting navigation satellites

Satellite navigation is headed closer to users. ESA’s Navigation Directorate is planning an in-orbit demonstration with new navigation satellites that will orbit just a few hundred kilometres up in space, supplementing Europe’s 23 222-km-distant Galileo satellites. Operating added-value signals, these novel so-called ‘LEO-PNT’ satellites will investigate a new multi-layer satnav system-of-systems approach to deliver seamless Positioning, Navigation and Timing services that are much more accurate, robust and available everywhere.

A new composite image of Saturn show its rings in unprecedented detail

A newly processed image, comprising 41 observations by NASA's retired Cassini mission, provides insights into the origins of Saturn's rings.

The 2022 Orionid meteor shower put on a show for skywatchers around the world (gallery)

The Orionid meteor shower lit up the skies around the world in 2022, and luckily many of our readers were able to catch wonderful images of the "shooting stars."

Opportunity Mars rover leader on 'Good Night Oppy' film, giving up Saturn

Steve Squyres, the principal investigator of the Opportunity mission, could have switched to Saturn. But learning about water on Mars kept him going on one mission for 30 years.

Craters and cracks on Mars

Lucy Took This Picture of Earth as it was Making its Gravity Assist Maneuver

We may take it for granted, but every day we receive picture postcards from the robotic travelers we have sent out to explore our Solar System. Usually, we get to see faraway planets, moons, asteroids, or comets. But sometimes we get to see ourselves.

Space station instrument spots methane 'super-emitters' on Earth

A powerful eye in the sky is helping scientists spy "super-emitters" of methane, a greenhouse gas about 80 times more potent than carbon dioxide.

Hubble Looks at Newly Forming Stars in a Stellar Nursery

When we look at images of star birth regions, they look both placid and active at the same time. That’s nowhere more true than in a stellar nursery associated with a so-called “Herbig-Haro” object. A recent image from Hubble Space Telescope zeroed in on two called “HH 1” and “HH 2”. It looked at the turbulence associated with a nearby newborn star system.

Samples Returned From Mars Will be Protected by a Micrometeorite Shield

In a few years, NASA and the ESA will conduct the long-awaited Mars Sample Return (MSR) mission. This mission will consist of a lander that will pick up the samples, an ascent vehicle that will send them to orbit, an orbiter that will return them to Earth, and an entry vehicle that will send them to the surface. This will be the first time samples obtained directly from Mars will be returned to Earth for analysis. The research this will enable is expected to yield new insights into the history of Mars and how it evolved to become what we see today.

Maybe We Don’t See Aliens Because Nobody Wants to Come Here

The Fermi Paradox won’t go away. It’s one of our most compelling thought experiments, and generations of scientists keep wrestling with it. The paradox pits high estimates for the number of civilizations in the galaxy against the fact that we don’t see any of those civs. It says that if rapidly expanding civilizations exist in the Milky Way, one should have arrived here in our Solar System. The fact that none have implies that none exist.
