This is an illustration of a distant galaxy with an active quasar at its center. A quasar emits exceptionally large amounts of energy generated by…
New simulation-based study on sleeping cataclysmic binaries supports contested 35-year-old predictions, shows that observable novae are just “tip of the iceberg.” Almost 35 years ago,…
Model developed by Brazilian researchers shows chaotic phase that placed objects in current orbits beginning within first 100 million years after formation of giant planets.…

Is this what the heliosphere looks like? New research suggests so. The size and shape of the magnetic “force field” that protects our solar system…
Artist impression of a double sunset on a ‘Tatooine’ exoplanet forming in a circumbinary disk that is misaligned with the orbits of its binary stars.…

The image of a black hole has a bright ring of emission surrounding a “shadow” cast by the black hole. This ring is composed of…
This image shows the sum of 15 independent tracings of the spiral structure of the same galaxy displayed using a violet to red rainbow color…
This illustration shows a nightside view of the exoplanet WASP-76b. The ultra-hot giant exoplanet has a dayside where temperatures climb above 2400 degrees Celsius, high…
An active galactic nucleus, or quasar, hosts a black hole with an accretion disk of matter orbiting around and two jets of plasma beaming outward.…
The Illustration is an artist view of one of the SPECULOOS telescopes, with the eclipsing binary brown dwarf in the sky. The third red dot,…
Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray space observatories, along with radio telescopes on ground, have spotted the aftermath of the most powerful explosion…
Despite Mercury’s daytime Vulcan heat, there is permanent ice at the poles, according to data and images from a NASA probe that visited Mercury in…
The Earth and Moon have distinct oxygen compositions and are not identical in oxygen new research suggests. Credit: UNM Scientists Find Earth and Moon Not…
