Hubble captures majestic barred spiral galaxy NGC 6956

Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly. NGC 6956 is a barred spiral galaxy, a common type of spiral galaxy with a bar-shaped structure of stars in its center. This galaxy ...

'Early dark energy' could explain the crisis in cosmology

In 1916, Einstein finished his theory of general relativity, which describes how gravitational forces alter the curvature of spacetime. Among other things, this theory predicted that the universe is expanding, which was confirmed ...

Machine learning tools autonomously classify 1,000 supernovae

Astronomers at Caltech have used a machine learning algorithm to classify 1,000 supernovae completely autonomously. The algorithm was applied to data captured by the Zwicky Transient Facility, or ZTF, a sky survey instrument ...

The most precise accounting yet of dark energy and dark matter

Astrophysicists have performed a powerful new analysis that places the most precise limits yet on the composition and evolution of the universe. With this analysis, dubbed Pantheon+, cosmologists find themselves at a crossroads.

Exploring the origin of the supersoft X-ray light curve

By simulating the feedback of the white dwarf (WD) to the periodic mass transfer driven by the X-ray irradiation on its companion, researchers led by Ph.D. candidate Zhao Weitao and Prof. Meng Xiangcun from the Yunnan Observatories ...

AI helps discover new space anomalies

The SNAD team, an international network of researchers including Matvey Kornilov, Associate Professor of the HSE University Faculty of Physics, has discovered 11 previously undetected space anomalies, seven of which are supernova ...

The star that survived a supernova

A supernova is the catastrophic explosion of a star. Thermonuclear supernovae, in particular, signal the complete destruction of a white dwarf star, leaving nothing behind. At least that's what models and observations suggested.
