Lightsails could reach distant star systems
A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.
View ArticleStraight shot: Hubble investigates galaxy with nine rings
NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf galaxy -- shot...
View ArticleWobbling stars reveal hidden companions in Gaia data
Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to...

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets.
View ArticleLargest radio jet ever seen in the early universe
Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have...
View ArticleAlien ocean could hide signs of life from spacecraft
A new study focusing on Enceladus, a moon of Saturn, shows that the physics of alien oceans could prevent evidence of deep-sea life from reaching places where we can detect it.
View ArticleMultinational research project shows how life on Earth can be measured from...
Measurements and data collected from space can be used to better understand life on Earth. An ambitious, multinational research project has demonstrated that Earth's biodiversity can be monitored and...
View ArticleTemperamental stars are distorting our view of distant planets
'Temperamental' stars that brighten and dim over a matter of hours or days may be distorting our view of thousands of distant planets, suggests a new study.
View ArticleEuclid discovers a stunning Einstein ring
Euclid, the European Space Agency's dark Universe detective, has made an astonishing discovery -- right in our cosmic backyard.
View ArticleFirst detection of an ultra-high-energy neutrino
Scientists have just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world. This exceptional discovery opens up new perspectives for understanding...
View ArticleTidal energy measurements help scientists understand Titan's composition,...
Scientists are studying Saturn's moon Titan to assess its tidal dissipation rate, the energy lost as it orbits the ringed planet with its massive gravitational force. Understanding tidal dissipation...

Jumping workouts could help astronauts prevent the type of cartilage damage they are likely to endure during lengthy missions to Mars and the Moon, a new study suggests. The researchers found that mice...
View ArticlePhoenix galaxy cluster in the act of extreme cooling
New findings explain the Phoenix cluster's mysterious starburst. Data confirm the cluster is actively cooling and able to generate a huge amount of stellar fuel on its own.
View Article'Game changing' release of Type Ia Supernovae data may hold key to the...
A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe.
View ArticleAstronomers gauge livability of exoplanets orbiting white dwarf stars
Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a...
View ArticleCreation of black holes without singularities through pure gravity
Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying how...
