A Rare Object Found Deep in the Kuiper Belt
Despite the powerful telescopes that modern astronomers have to work with, the distant reaches of the Solar System are still mysterious. Not much sunlight pierces these regions, and there are strong hints that undiscovered objects lurk there. The objects that astronomers have discovered in these dim reaches are primordial, and their orbits suggest the presence of more undiscovered objects. Piecing it all together is a challenge.
2 billion-year-old moon rock found in Africa reveals secret lunar history
The basaltic meteorite is a piece of lunar rock that formed in a lava flow 2.35 billion years ago, long after volcanism on the moon was supposed to have ended.
A vast shadow will sweep over Saturn's cloud tops early on July 18: Here's how to see it
Titan shadow transit seasons occurs just once every 15 years.

Student Led Mission Designs Highlight The Challenges Of Engineering In Space
There are plenty of engineering challenges facing space exploration missions, most of which are specific to their missions objectives. However, there are some that are more universal, especially regarding electronics. A new paper primarily written by a group of American students temporarily studying at Escuela Tecnica Superior de Ingenieria in Madrid, attempts to lay out plans to tackle several of those challenges for a variety of mission architectures.
'Doghouse' days of summer — Boeing's Starliner won't fly again until 2026, and without astronauts aboard
NASA and Boeing are still working on the thruster issues that Starliner experienced on its first crewed flight last year, and the spacecraft's next mission will likely launch without astronauts.
Vigil: ESA’s space weather reporter in deep space
Video: 00:01:51
Space weather ‘reporter’ Vigil will be the world’s first space weather mission to be permanently positioned at Lagrange point 5, a unique vantage point that allows us to see solar activity days before it reaches Earth. ESA’s Vigil mission will be a dedicated operational space weather mission, sending data 24/7 from deep space.
What has Webb Taught Us About Rocky Exoplanets So Far?
The hunt for potentially habitable rocky planets in our galaxy has been the holy grail of exoplanet studies for decades. While the discovery of over 5,900 exoplanets in over 4.400 planetary systems has been a remarkable achievement, only a small fraction (217) have been confirmed as terrestrial - aka. rocky or "Earth-like." Furthermore, obtaining accurate information on a rocky exoplanet's atmosphere is very difficult, since potentially habitable rocky planets are much smaller and tend to orbit closer to their stars.
The Most Massive Black Hole Merger Ever
In 2016, scientists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) made history with the first-ever detection of Gravitational Waves (GWs). These events, originally predicted by Einstein's Theory of Relativity, are caused by the merger of dense objects like neutron stars and black holes. Since then, the LIGO team partnered with the Virgo Gravitational Wave Interferometer (Virgo) in Italy and the Kamioka Gravitational Wave Detector (KAGRA) in Japan to form the LIGO-Virgo-KAGRA (LVK) Collaboration.
These Massive Runaway Stars Were Birthed in a Chaotic Cluster
Stars are born in clusters, and the early days in these clusters are messy. Stars move chaotically and haven't settled into regular routines. Inevitably, some stars are kicked out of their birth clusters through all of the gravitational interactions.
A Star is Dissolving its Baby Planet
Stars and planets are naturally associated with one another. While some planets have gone rogue and are drifting through space, the vast majority are in solar systems, where they're gravitationally bound and orbit their stars in predictable ways. But some planets stray too close to their stars, with dire consequences. These exoplanets have something to teach us about the exoplanet population.
