The exploration of celestial bodies and cosmic phenomena beyond Earth. This field seeks to uncover the mysteries of the universe, including the nature of stars, planets, galaxies, and the laws governing space and time.
Astronomers using the James Webb Space Telescope have confirmed the first known case of a supermassive black hole expelled from its host galaxy, identifying a fast moving object generating a supersonic bow shock in a galaxy system about 8.8 billion light years away.
NASA’s SPHEREx space observatory completed its first all-sky infrared mosaic, six months after beginning systematic observations from Earth orbit, delivering the most spectrally detailed panoramic view of the universe ever produced.
Astronomers using the NASA/ESA Hubble Space Telescope have identified the aftermath of two massive planetesimal collisions in the nearby Fomalhaut star system.
Astronomers at W. M. Keck Observatory in Hawaiʻi have observed AT2025ulz, a possible first-of-its-kind superkilonova that appears to have exploded twice — first as a supernova, then as a kilonova — on August 18, 2025.
An international team led by the University of Oxford has identified a 15-megaparsec-long rotating filament of galaxies about 140 million light-years away, one of the largest spinning structures ever observed.
New analyses of interstellar comet 3I/ATLAS show that this rare visitor is a carbon-rich, metal-bearing body with an unusually bright coma dominated by carbon dioxide, suggesting a complex chemistry possibly linked to catalytic and cryovolcanic processes.
Scientists have confirmed that asteroid Bennu contains ribose, glucose, and other foundational sugars of life — the final missing pieces of prebiotic chemistry beyond Earth. The discovery shows that the building blocks of RNA and metabolic energy were present in the early solar system, strengthening the view that life’s chemistry began as a cosmic process rather than a strictly terrestrial one.
Asteroid 2022 RD2, a 5–11 m (16–36 feet) near-Earth object from the Arjuna group, will be temporarily captured by Earth three times between November 2043 and July 2044, creating the first predicted triple mini-moon sequence ever observed.
A team from the Higher School of Economics (HSE) and the Space Research Institute of the Russian Academy of Sciences (IKI RAS) analyzed seven years of satellite data and confirmed that Earth produces a natural radio emission called the hectometer continuum — a faint signal that vanished in mid-2022 as the Sun’s activity increased.
A new mosaic from the GREGOR solar telescope shows the last 30 minutes before a major solar flare, displaying how twisted magnetic filaments and sunspot rotation stressed the solars magnetic field until it released an X1.2 eruption.
