Looking back in time to watch for a different kind of black hole
A simulation has suggested what astronomers should look for if they search the skies for a direct collapse black hole in its early stages.

BUFFALO charges towards the earliest galaxies
The NASA/ESA Hubble Space Telescope has started a new mission to shed light on the evolution of the earliest galaxies in the Universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings. The first observations show the galaxy cluster Abell 370 and a host of magnified, gravitationally lensed galaxies around it.

Artificial intelligence helps track down mysterious cosmic radio bursts
Fast radio bursts are powerful blasts of energy from across the cosmos caused by unknown events, perhaps emissions from a collapsed and highly magnetized neutron star. One FRB source has attracted attention because it repeats. Researchers recorded radio data from this source and scraped it with a new machine learning algorithm that uncovered 72 new bursts undetected by normal techniques.

Galactic 'wind' stifling star formation is most distant yet seen
For the first time, a powerful 'wind' of molecules has been detected in a galaxy located 12 billion light-years away. Probing a time when the universe was less than 10 percent of its current age, astronomers sheds light on how the earliest galaxies regulated the birth of stars to keep from blowing themselves apart.

Unstoppable monster in the early universe
Astronomers obtained the most detailed anatomy chart of a monster galaxy located 12.4 billion light-years away. Using the Atacama Large Millimeter/submillimeter Array (ALMA), the team revealed that the molecular clouds in the galaxy are highly unstable, which leads to runaway star formation.

Astronomers identify some of the oldest galaxies in the universe
Astronomers have found evidence that the faintest satellite galaxies orbiting our own Milky Way galaxy are among the very first galaxies that formed in our universe.

Under pressure, hydrogen offers a reflection of giant planet interiors
Lab-based mimicry allowed an international team of physicists to probe hydrogen under the conditions found in the interiors of giant planets -- where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity.

Hubble paints picture of the evolving universe
Hubble and other space and ground-based telescopes, astronomers have assembled one of the most comprehensive portraits yet of the universe's evolutionary history.

Sprawling galaxy cluster found hiding in plain sight
Scientists have uncovered a sprawling new galaxy cluster hiding in plain sight. The cluster, which sits a mere 2.4 billion light years from Earth, is made up of hundreds of individual galaxies and surrounds an extremely active supermassive black hole, or quasar.

Early opaque universe linked to galaxy scarcity
A team of astronomers has made a surprising discovery: 12.5 billion years ago, the most opaque place in the universe contained relatively little matter.

Exoplanets where life could develop as it did on Earth
Scientists have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist.

X-ray technology reveals never-before-seen matter around black hole
Scientists have clarified how gravity affects the shape of matter near the black hole in binary system Cygnus X-1. Their findings may help scientists further understand the physics of strong gravity and the evolution of black holes and galaxies.

Young galaxy's halo offers clues to its growth and evolution
A team of astronomers has tested a new way of studying the properties of the gaseous halo surrounding a galaxy using W. M. Keck Observatory's new instrument, the Keck Cosmic Web Imager. The analysis is the first of its kind and could offer clues about galaxy formation and evolution.

CALET succeeds in direct measurements of cosmic-ray electron spectrum up to 4.8 TeV
Researchers have succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET). Observations by CALET are expected to reveal the mysteries of cosmic-rays and nature of dark matter in the future.

NASA's new mini satellite will study Milky Way's halo
A new mission called HaloSat will help scientists search for the universe's missing matter by studying X-rays from hot gas surrounding the Milky Way galaxy.

Planck: Final data from the mission lends support to the standard cosmological model
With its increased reliability and its data on the polarization of relic radiation, the Planck mission corroborates the standard cosmological model with unrivaled precision for these parameters, even if some anomalies still remain.

Supersharp images from new VLT adaptive optics
ESO's Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography -- and has captured remarkably sharp test images of the planet Neptune and other objects. The MUSE instrument working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope.

VERITAS supplies critical piece to neutrino discovery puzzle
The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle.

Hubble and Gaia team up to fuel cosmic conundrum
Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe's expansion rate.
