Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this year.

Scientists have identified a new source of energetic particles near the Sun. These definitive observations were made by instruments aboard NASA's Parker Solar Probe, which detected the powerful phenomena as the spacecraft dipped in and out of the solar corona.

Tracing the origin of an ultra-hot exoplanet: The chemical composition of WASP-121b suggests that it formed in a cool zone of its natal disc, comparable to the region of gas and ice giants in our Solar System. Methane indicates unexpected atmospheric dynamics: Despite extreme heat, methane was detected on the nightside -- a finding that can be explained by strong vertical atmospheric circulation. First detection of silicon monoxide in a planetary atmosphere: Measurements of this refractory gas allow quantifying the rocky material the planet had accumulated.

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the most delicate experiments in existence to observe and understand our universe.

A series of studies sheds light on the origins and characteristics of intermediate-mass black holes.

The process of necrosis, a form of cell death, may represent one of the most promising ways to change the course of human aging, disease and even space travel, according to a new study.

A series of experiments support spectral data recently collected by the James Webb Space Telescope that found evidence that the icy surface of Jupiter's moon Europa is constantly changing. Europa's surface ice is crystallizing at different rates in different places, which could point to a complex mix of external processes and geologic activity affecting the surface.

Scientists have observed anyons -- quasiparticles that differ from the familiar fermions and bosons -- in a one-dimensional quantum system for the first time. The results may contribute to a better understanding of quantum matter and its potential applications.

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays.

Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur from images caused by the Earth's atmosphere. Their ground-breaking results pave the way for deeper insight into coronal heating, solar eruptions, and space weather, and open an opportunity for new discoveries in the Sun's atmosphere.

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the moon and amplified its weak magnetic field.

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our understanding of how barred spiral galaxies, like our own Milky Way Galaxy, grow and evolve.

The puzzling behavior of Titan's atmosphere has been revealed. The team has shown that the thick, hazy atmosphere of Saturn's largest moon doesn't spin in line with its surface, but instead wobbles like a gyroscope, shifting with the seasons.

A multi-sensor detection of an intense gamma-ray flash, which occurs when two lightning leaders collided, has been observed. Observations across a wide radiation spectrum enabled precise measurement of the electric current produced during this extreme event, and demonstrated that the gamma-ray flash preceded the collision of the lightning leaders between the thundercloud and the ground.

The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study.

Scientists have discovered how solar activity affects the velocity distribution and evolution of helium pickup ions.

Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results show that this radiation dampens the wounded galaxy's ability to form new stars.

In the intriguing realm of star-forming galaxies, the key factor isn't the total amount of gas but rather its strategic distribution within the galaxy.

Astronomers have filled a large gap in knowledge about Mars' water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like, suggesting that less of the planet's water may have been available to become rain and refill lakes and oceans.

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with another galaxy, or have been tossed out of the core after interacting with two other black holes. This is the first ever optically discovered off-nuclear tidal disruption event. Eventually, the two could merge and produce ripples of gravitational waves.
