Nearly a decade in the making, exoplanet-hunting instrument installed in Hawaii
Atop a dormant volcano in Hawaii, an extremely delicate instrument-designed to help scientists find distant worlds-is scattered across the floor in hundreds of pieces. "Imagine trying to assemble one of those huge LEGO sets, except there's no instruction book; you've done it once before, but then you had to take it all apart and put it in little bags," said Jacob Bean, associate professor of astronomy and astrophysics at the University of Chicago.

Growing old together: a sharper look at black holes and their host galaxies
Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University. The "special relationship" between supermassive black holes (SMBHs) and their hosts - something astronomers and physicists have observed for quite a while - can now be understood as a bond that begins early in a galaxy's formation and has a say in how both the galaxy and the SMBH at its center grow over time, the researchers note.

More accurate than expected
More accurate than expected
Despite their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.

Get ready for more interstellar objects, Yale astronomers say
Gregory Laughlin and Malena Rice weren't exactly surprised a few weeks ago when they learned that a second interstellar object had made its way into our solar system. The Yale University astronomers had just put the finishing touches on a new study suggesting that these strange, icy visitors from other planets are going to keep right on coming.

Enigmatic radio burst illuminates a galaxy's tranquil halo
Enigmatic radio burst illuminates a galaxy’s tranquil halo
Astronomers using ESO's Very Large Telescope have for the first time observed that a fast radio burst passed through a galactic halo. Lasting less than a millisecond, this enigmatic blast of cosmic radio waves came through almost undisturbed, suggesting that the halo has surprisingly low density and weak magnetic field.

A radio that searches for dark matter
A radio that searches for dark matter
An "out there" theory inspired the development of the Dark Matter Radio, a device that could explain the mysterious matter that makes up 85 percent of the mass of our universe. A team of Stanford University researchers are on a mission to identify dark matter once and for all. But first, they'll need to build the world's most sensitive radio.

New satellite looking at how Earth is losing its cool gets the go-ahead
New satellite looking at how Earth is losing its cool gets the go-ahead
A satellite that will measure Earth's energy budget, helping to improve climate change predictions, has been selected as a future mission by ESA. FORUM (Far-infrared Outgoing Radiation Understanding and Monitoring) will measure radiation emitted by Earth into space. This will provide new insight into the planet's energy budget - how much energy it receives from the Sun, how much it retains, and how much it remits to space.

Opinion: Five climate change science misconceptions - debunked
Professor Mark Maslin (UCL Geography) writes about common climate change myths and explains how each can be disproven. The science of climate change is more than 150 years old and it is probably the most tested area of modern science. However the energy industry, political lobbyists and others have spent the last 30 years sowing doubt about the science where none really exists.

Opinion: How we detected water on a potentially habitable exoplanet for the first time
Angelos Tsiaras (UCL Physics & Astronomy) writes about the methods used to discover water vapour in the atmosphere of K2-18 b, the first potentially habitable planet outside of our solar system. With more than 4,000 exoplanets - planets orbiting stars other than our sun - discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe.

Dust from a giant asteroid crash caused an ancient ice age
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species. The cause of this ice age was a mystery, until now: a new study by a group of scientists including a University of Chicago professor argues that the ice age was caused by global cooling, triggered by extra dust in the atmosphere from a giant asteroid collision in outer space.
