We can"t see the first stars yet, but we can see their direct descendants
If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations of stars after that. So ou.....»»
Presence of atomic oxygen confirmed on both day and night sides of Venus
A multi-institutional team of astrophysicists from Germany has made the first direct observation of oxygen atoms in the day side atmosphere of Venus. In their project, reported in the journal Nature Communications, the group studied data from the Str.....»»
This is a first: An exoplanet in a polar circumbinary disk surrounding two stars
We live in an age of exoplanet discovery. One thing we've learned is not to be surprised by the kinds of exoplanets we keep discovering. We've discovered planets where it might rain glass or even iron, planets that are the rocky core remnants of gas.....»»
Searching for the supernova neutrino background to the universe
It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to the end of this article. The more massive stars.....»»
Oldest known samples of brittle stars from supercontinent Gondwana discovered in South Africa
A small team of paleontologists with members from Rhodes University, in South Africa, the National Museum of Natural History, Luxembourg City, and the University of Oxford, in the U.K., has discovered the oldest known brittle star samples from the su.....»»

An exo-Neptune beat the odds and kept its atmosphere
As planet-hunting scientists find more and more planets, they've encountered some puzzles. One of them concerns the lack of Neptune-size worlds orbiting close to their stars. Astronomers think that these planets aren't massive enough to retain their.....»»
Astronomers discover infant "escaping star"
Stars escape from their birth place and eventually become dispersed across the galaxy. This is an important process in galactic evolution. Theoretical studies suggest two possible reasons why stars escape. First, stars may be ejected due to interacti.....»»
Astronomers want JWST to study the Milky Way core for hundreds of hours
To understand the universe, we need to understand the extreme processes that shape it and drive its evolution. Things like supermassive black holes (SMBHs,) supernovae, massive reservoirs of dense gas, and crowds of stars both on and off the main seq.....»»
Chaotic jumble of merging spiral galaxies hints at possible fate of Milky Way and Andromeda galaxies
The swirling arms of a spiral galaxy are among the most recognized features in the cosmos: long sweeping bands spun off from a central core, each brimming with dust, gas, and dazzling pockets of newly formed stars. Yet this opulent figure can warp in.....»»

Why NASA"s Roman mission will study Milky Way"s flickering lights
NASA's Nancy Grace Roman Space Telescope will provide one of the deepest-ever views into the heart of our Milky Way galaxy. The mission will monitor hundreds of millions of stars in search of tell-tale flickers that betray the presence of planets, di.....»»
Simulating space to explore the great mystery of interstellar chemistry
The universe is more than 13 billion years old and space is often depicted as a vast, empty vacuum. Other than planets and stars, there's nothing there, right? Actually, space is littered with complex, carbon-based molecules. However, the range of mo.....»»
Astronomers carry out largest ever cosmological computer simulation
An international team of astronomers has carried out what is believed to be the largest ever cosmological computer simulation, tracking not only dark but also ordinary matter (such as planets, stars and galaxies), giving us a glimpse into how our uni.....»»
In 1952, a group of three "stars" vanished—astronomers still can"t find them
On July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photogra.....»»
LIGO surpasses the quantum limit
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes......»»
JWST looks at the debris disk around a white dwarf
Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what.....»»
