Astronomers discover a pair of fates of spiral stars at our universe’s gateway
In this photo, the first white dwarf captures the binary at the moment it just explodes, rushing through the material towards a nearby companion in the explosion cusp. The event takes place in about 23 billion years, but in just four seconds both stars explode.

Astronomers find gas exoplanets that have formed earlier than previously thought
Credit: Unsplash/CC0 Public Domain New research shows that a new look at past data reveals that a tumor with a Jupiter-like mass formed much earlier than previously thought. The results of the Ohio State University survey provide new information on the timing of accumulation. This is the process of accumulating large amounts of gases and solid particles rich in carbon…

Recent high -speed radio bursts question what the astronomers believed they knew.
The location of the high -speed radio burst indicated by the elliptical contour is located in the outskirts of the huge elliptical galaxy, which is the yellow elliptical. Credit: Gemini Observatory Astronomer Calvin Leon, astronomer, was newly established last summer to accurately identify the so -called high -speed radio burst (FRB) to accurately identify powerful radio waves emitted from somewhere…

Astronomers discover supermassive Grand Design spiral galaxy
Morphology and photometric redshift of Zhúlóng. Credit: Xiao et al., 2024. An international team of astronomers used the James Webb Space Telescope (JWST) to detect a new grand design spiral galaxy as part of a panoramic survey. The newly discovered galaxy, named Zhúlóng, is so massive that it appears to be the most distant spiral galaxy yet identified. The findings…

A clever trick to cook young stars discovered for the first time – astronomers highlight magnetic field as missing ingredient
Astronomers have discovered evidence of a magnetic field associated with a disk of gas and dust hundreds of light-years in diameter deep within two merging galaxies known as Arp220 (pictured). Credits: NASA, ESA, Hubble Legacy (STScl/AURA), ESA, Hubble Collaboration, A. Evans (University of Virginia Charlottesville/NRAO/Stony Brook University) For the first time, astronomers have discovered the missing ingredient to cook stars…

Astronomers discover more dark comets
This artist’s concept shows the interstellar object 1I/2017 U1 (Oumuamua) discovered in 2017. Although not a dark comet per se, ‘Oumuamua’s movement through the solar system has helped researchers better understand the nature of the 14 dark comets discovered so far. Credit: European Southern Observatory / M. Kornmesser The first dark comet (an object that looks like an asteroid but…

Astronomers discover hundreds of new galaxies by ignoring the avoidance zone
A galaxy observed within the Vera supercluster. Credit: Sambatriniaina HA Rajohnson et al. There are regions of the sky that astronomers are afraid to see. Filled with a cloud of black dust, hiding an invisible mass. It has a very large mass and attracts the Milky Way and other galaxies. Well, that may be an exaggeration, but it’s true. This…

Astronomers predict potentially dangerous comet’s trajectory from meteor shower
Illustration of a long-period comet and the Oort cloud. Credit: National Astronomical Observatory of Japan Comets have long been considered omens and omens, and it’s easy to understand why. They first appear as faint smears of light in the sky, sometimes quickly disappearing, sometimes brighter than the planets, and accompanied by long, glowing tails. Although they have been observed throughout…

Innovative model offers new way for astronomers to analyze powerful cosmic explosions
The explosion of a massive star leads to the ejection of its outer shell, and this “ejecta” expands outward over time and interacts with the star’s surrounding medium upon its death. This interaction creates two shock waves and a contact discontinuity (collectively known as a “shell”) that dissipates kinetic energy in exchange for producing more light. Eric Coughlin’s new model…

Astronomers map ‘danger zone’ of planet-forming disks in star clusters
X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image processing: NASA/CXC/SAO/N. walk Most stars form collections called clusters or federations that contain very massive stars. These massive stars emit large amounts of high-energy radiation that can destroy relatively fragile disks of dust and gas that are in the process of merging to form new planets. A team of astronomers uses NASA’s…
