Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars -- possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magnetic field emerged from behind a thick shell of debris from the explosion.

NASA's Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the apparent edges of many galaxies. Missions like the Hubble and James Webb space telescopes would have to patch together hundreds of small images to see these structures around nearby galaxies in full. Roman will do so in a single snapshot. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter.

Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps of dust. Instead, the observations took a surprise turn, revealing the most complicated and eccentric debris disk observed to date.

Astronomers discovered a multiplanet system just 33 light-years from Earth, making it one of the closest known multiplanet systems. The system likely hosts at least two terrestrial, Earth-sized planets.

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Now we can see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region.

Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ago.

The unusual behavior of sulphur in Venus' atmosphere cannot be explained by an 'aerial' form of extra-terrestrial life, according to a new study.

New study finds star-forming cloud's magnetic field is curiously twisted. Researchers believe a newborn star moved into another young star's stellar envelope to form a binary star system. The interloper shifted the cloud's dynamics, twisting its magnetic field. The new findings provide insight into binary star formation and how magnetic fields influence the earliest stages of developing stars.

A new study using hydrodynamical simulations reveals the forces acting on a planet when it is swallowed by an expanding star. The results show that the interactions of a substellar body (a planet or brown dwarf) with the hot gas in the outer envelope of a sun-like star can lead to a range of outcomes depending on the size of the engulfed object and the stage of the star's evolution. The dynamics and possible outcomes of planetary engulfment are poorly understood, but it is thought to be a relatively common fate for planetary systems.

Astronomers have discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field -- so-called gravitational microlensing.

Scientists have now begun to announce the first results from the analysis of a handful of dirt that Hayabusa2 managed to scoop off the surface of a speeding asteroid. What they found suggests that this asteroid is a piece of the same stuff that coalesced into our sun four-and-a-half billion years ago.

Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be imaged around stars in almost three decades of searches. An international team has directly imaged a remarkable four new brown dwarfs thanks to a new innovative search method.

A new study offers direct evidence showing where near-light speed particle acceleration occurs inside the largest explosion known in the solar system, the solar flare.

Astronomers have developed a new code to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion Nebula shows that its off-center bubble of ionized gas was caused by a massive star that was pushed out of the newborn cluster but is now falling back in.

Clouds of ultralight particles can form around rotating black holes. A team of physicists now show that these clouds would leave a characteristic imprint on the gravitational waves emitted by binary black holes.

A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun.

An international research team has investigated the chances of survival of kombucha cultures under Mars-like conditions. Kombucha is known as a drink, sometimes called tea fungus or mushroom tea, which is produced by fermenting sugared tea using kombucha cultures -- a symbiotic culture of bacteria and yeast. Although the simulated Martian environment destroyed the microbial ecology of the kombucha cultures, surprisingly, a cellulose-producing bacterial species survived.

NASA scientists and engineers give new details about the Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Researchers have now developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet's stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

An international team of astronomers used a database combining observations from the best telescopes in the world, including the Subaru Telescope, to detect the signal from the active supermassive black holes of dying galaxies in the early Universe. The appearance of these active supermassive black holes correlates with changes in the host galaxy, suggesting that a black hole could have far reaching effects on the evolution of its host galaxy.
