For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA's James Webb Space Telescope's Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.

On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the Moon. In anticipation of this historic event, scientists are publishing their predictions for the unique materials that may be found in the CE-6 samples.

Astronomers uncovered that a well-known X-ray binary, whose exact nature has been a mystery to scientists until now, is actually a hidden ultraluminous X-ray source.

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.

What actually happens to the human body in space? While scientists and researchers have heavily researched how various factors impact the human body here on Earth, the amount of information available about changes that occur in the body in space is not as well-known. Scientists have been studying for years how the body, specifically on the molecular side, changes in space. Recently, findings depict how the modern tools of molecular biology and precision medicine can help guide humanity into more challenging missions beyond where we've already been.

Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but were transported to the outer solar system. New research shows that for this to have happened, the protoplanetary disk of our solar system had to have been doughnut-shaped because the refractory metals could not have crossed the large gaps in a target-shaped disk of concentric rings. The paper suggests that the refractory metals moved outward as the protoplanetary disk rapidly expanded, and were trapped in the outer solar system by Jupiter.

Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating, magnetic wind that they believe is helping a galaxy's central supermassive black hole to grow. The swirling wind, revealed with the help of the ALMA telescope in nearby galaxy ESO320-G030, suggests that similar processes are involved both in black hole growth and the birth of stars.

Geologists studied Titan's shorelines and showed through simulations that coastlines of the moon's methane- and ethane-filled seas have likely been shaped by waves. Until now, scientists have found indirect and conflicting signs of wave activity, based on Cassini images of Titan's surface.

Jupiter's iconic Great Red Spot has persisted for at least 190 years and is likely a different spot from the one observed by the astronomer Giovanni Domenico Cassini in 1665, a new study reports. The Great Red Spot we see today likely formed because of an instability in the planet's intense atmospheric winds, producing a long, persistent atmospheric cell, the study also finds.

The severity of anxiety and depressive symptoms in the planetary science community is greater than in the general U.S. population, according to a new study.

Gravitational changes experienced by astronauts during space travel can cause fluids within the body to shift. This can cause changes to the cardiovascular system, including vessels in and around the eyes. These fluid shifts may be related to a phenomenon known as Spaceflight Associated Neuro-ocular Syndrome (SANS), which can cause astronauts to experience changes in eye shape and other ocular symptoms.

Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.

New simulations show that hot neutrinos created at the interface of merging binary neutron stars are briefy trapped and remain out of equilibrium with the cold cores of the stars for 2 to 3 milliseconds.

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory's Very Large Telescope (ESO's VLT), to track how the galaxy's brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy -- likely the result of the sudden awakening of the massive black hole at its core.

Detecting marine debris from space is now a reality, according to a new study. Until now, the amount of litter -- mostly plastic -- on the sea surface was rarely high enough to generate a detectable signal from space. However, using supercomputers and advanced search algorithms, the research team has demonstrated that satellites are an effective tool for estimating the amount of litter in the sea.

In a breakthrough discovery that challenges the conventional understanding of cosmology, scientists have unearthed new evidence that could reshape our perception of the cosmos. New research shows that rotation curves of galaxies stay flat indefinitely far out, corroborating predictions of modified gravity theory as an alternative to dark matter.

Using a specially designed 3D printed vacuum system, scientists have developed a way to 'trap' dark matter with the aim of detecting domain walls, this will be a significant step forwards in unravelling some of the mysteries of the universe.

Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the Universe's earliest formation.

A team of scientists used NASA's James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
