Using high-resolution data from the one-meter New Vacuum Solar Telescope (NVST), a research team led by Prof. Yan Xiaoli from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) has conducted an in-depth study on the physical properties and oscillations of chromospheric fibrils surrounding a quiescent filament.

New research from Rice University suggests that the giant planet Jupiter reshaped the early solar system in dramatic ways, carving out rings and gaps that ultimately explain one of the longest-standing puzzles in planetary science: why many primitive meteorites formed millions of years after the first solid bodies.

Every year, we shoot several thousand satellites and other objects out into space. When satellites die, they become space trash that threatens aerospace safety.

A team of astronomers led by Paulo Cortes, a scientist with the U.S. National Science Foundation National Radio Astronomy Observatory and the Joint ALMA Observatory, have made a groundbreaking discovery about how young star systems grow.

In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the sun’s gravitational influence.

In the distant past, the solar system was rife with impacts and collisions. Millions of rocky objects zoomed chaotically through the system, smashing into each other in collisional cascades. Over time, many of them eventually became part of the rocky planets. What’s left of the space rocks are mostly gathered in the main asteroid belt. […]
A novel imaging technique used for the first time on a ground-based telescope has helped a UCLA-led team of astronomers to achieve the sharpest-ever measurement of a star’s surrounding disk, revealing previously unseen structure.

Scientists have released a new study on the arXiv preprint server that catalogs the universe by mapping huge clusters of galaxies.

A radio pulsar is like a cosmic lighthouse, a highly dense, rapidly rotating star that emits beams of radio waves. If Earth happens to be in the path, a “pulse” of radio waves will be detected.

Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are captured by neon and magnesium nuclei.

Using ESA’s Gaia satellite, astronomers have detected 87 stellar streams associated with globular clusters (GCs) in our Milky Way galaxy. The discovery, which doubles the number of known GC stellar streams, was detailed in a research paper published October 16 on the arXiv pre-print server.

In the 1960s, Frank Sinatra’s song “Fly Me to the Moon” became closely associated with the Apollo missions. The optimistic track was recorded in 1964, when US success against the Soviet Union in the moon race was not assured.

Astronomers using the James Webb Space Telescope (JWST) have captured the most detailed look yet at how galaxies formed just a few hundred million years after the Big Bang—and found they were far more chaotic and messy than those we see today.

The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulfur dioxide and ozone. Despite being preliminary, these images mark a major milestone in Europe’s ability to monitor air quality all the way from geostationary orbit, 36,000 kilometers above Earth.

A powerful new telescope has captured its first glimpse of the cosmos, and could transform our understanding of how stars, galaxies and black holes evolve.
