Distant galaxy fades 20-fold in just two decades, challenging how supermassive black holes evolve

An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a galaxy about 10 billion light-years away whose brightness dropped to one-twentieth of its original level in just 20 years. By combining multiwavelength observations with archival data spanning several decades, the researchers concluded that the fading […]

Webb and Hubble share the most comprehensive view of Saturn to date

NASA’s James Webb Space Telescope and Hubble Space Telescope have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways. Observing in complementary wavelengths of light, the two space observatories provide scientists with a richer, more layered understanding of the gas giant’s atmosphere.

XRISM clocks hot wind of galaxy M82 at 2 million mph

For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation. The material is moving more than 2 million miles (over 3 million kilometers) per hour and appears to be the […]

JWST reveals most distant red galaxy yet at redshift 11.45

Using the James Webb Space Telescope (JWST), astronomers have discovered a new red galaxy at a redshift of approximately 11.45. The newfound galaxy, which received designation EGS-z11-R0, turns out to be the most distant red galaxy detected to date. The discovery was detailed in a paper published March 18 on the arXiv pre-print server.

Developing optical vortex phase masks for the detection of habitable worlds

A team of NASA researchers is developing new types of optical masks that could help enable the many orders of magnitude of starlight suppression needed for future space observatories to pick out very faint habitable exoplanets from the far brighter glare of their stellar hosts.

Unusual signal may prove existence of primordial black holes

It may well take years to prove, but a pair of University of Miami astrophysicists could be on the verge of a cosmic breakthrough that will confirm the existence of primordial black holes and the role they play in one of cosmology’s greatest mysteries.

Radio signals at the edge of extreme stars come from far beyond their surfaces

Pulsars are ultra-dense, rapidly spinning, and highly magnetized remnants of dead stars. They act like cosmic lighthouses, sending out regular pulses of radio waves and sometimes gamma rays in beams that sweep across the sky. A special class called millisecond pulsars spins hundreds of times per second and is among the most precise clocks in […]

From frontier to feedback loop: Expert explains why space must become circular

Materials scientist Dr. Yige Sun, from the Department of Materials and Linacre College at the University of Oxford, and the Faraday Institution, argues that as space becomes critical infrastructure for the global digital economy, its long-term viability depends on urgently transitioning from a linear to a circular model of development.

AI approach uncovers dozens of hidden planets in NASA’s TESS data

Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA’s Transiting Exoplanet Survey Satellite (TESS), a space mission that monitors the sky for the subtle dimming of starlight caused when planets pass in front of their host stars.
