Caption: Artist's illustration of two supermassive black holes (MBHs) within a galaxy. A tidal disruption event occurs around the supermassive black hole off the center of the galaxy, and material from a disintegrated star swirls into a bright accretion disk, which releases an energetic jet and produces two bright radio bursts.

Scientists Just Found the Oldest Bar Spiral Galaxy—and It's Monster

  • No comments
A massive barred spiral galaxy from 11.1 billion years ago shows never-before-seen star formation and gas dynamics. It could reshape our understanding of how galaxies like the Milky Way form.

Young stars feed on chaos to build planets

  • No comments
New research reveals that early stars do not operate in isolation – but rather absorb material from their chaotic surroundings using a cosmic adsorption mechanism, which directly affects the formation of planets.

New research using the ALMA telescope reveals that frequent and extremely intense bursts of radiation from Proxima Centauri could destroy the atmospheres of nearby planets and make them uninhabitable.

Target board or donut? Iron meteorites reveal the early form of our solar system

  • No comments
The formation of our solar system involved the accretion of gas and dust into a preplanetary disk, with meteorites providing important insights into its early composition.
An artist's impression of the large-scale landscape of FU~Ori. The image shows the currents created by the interaction between strong stellar winds triggered by the outburst and the remnant mantle from which the star formed. The stellar wind drives the shock wave into the mantle and the CO gas carried away by the shock is the new discovery of the ALMA observatory. Credit: NSF/NRAO/SDagnello

Astronomers solve the mystery of the dramatic 1936 eruption of FU Orionis

  • No comments
An unusual group of stars in the Orion constellation has revealed their secrets. FU Orionis, a double star system, first attracted the attention of astronomers in 1936, when the central star suddenly became

The James Webb Space Telescope reveals the unseen forces that shape planetary systems

  • No comments
Researchers studying the Orion Nebula with the James Webb Space Telescope found that ultraviolet radiation from massive stars prevents the formation of giant planets in young systems by scattering the building materials.
Astronomers have found water vapor in the disk around a young star right where planets are likely to form. In this image, the new observations from the ESO partner Atacama Large Millimeter/Submillimeter Array (ALMA) show the water vapor in shades of blue. Near the center of the disc, where the young star lives, the environment is hotter and the gas is brighter. The red rings are previous ALMA observations showing the distribution of dust around the star.Credit: ALMA (ESO/NAOJ/NRAO)/S. Facchini et al.

An amount of water at least three times greater than the water in all the Earth's oceans was discovered in the inner disk of the young Sun-like star HL Tauri, 450 light-years away from Earth, in the Taurus group
The galaxy cluster RXCJ0600-2007 imaged by the NASA/ESA Hubble Space Telescope, combined with gravitational lensing images of the distant galaxy RXCJ0600-z6, 12.4 billion light-years away, observed by ALMA (shown in red). Due to the gravitational lensing effect of the galaxy cluster, the image of RXCJ0600-z6 has been intensified and magnified, appearing to be divided into three or more parts.

Maps of filaments of matter filling the universe. The gas wires are shown in blue. The background maps are an optical image taken by the Subaru Telescope (left) and a millimeter wavelength image taken by the ALMA observatory (right). Existence of extensive gaseous structures and cosmic web wires discovered (left); and that the filaments connect several galaxies where there is a high rate of star formation (right). Credit: RIKEN
