Astronomers have detected extreme-velocity gas outflows powerful enough to empty entire galaxies of the raw material needed to form new stars — a find that could explain why so many early galaxies went dark.
Extreme cosmic winds strip galaxies of gas, halting the formation of new stars.
The phenomenon may explain the abundance of 'dead' galaxies in the early Universe.
The mechanism is self-regulating: faster growth triggers stronger winds that shut growth down.
On June 14, 1962, European nations signed the founding agreement of the organisation that would eventually become ESA — today one of the world's leading space agencies.
On June 14, 1962, ESRO was founded as the direct forerunner of the European Space Agency.
ESA was officially established in 1975 through the merger of ESRO and the European launcher organisation.
The agency today has 22 member states and conducts missions throughout the solar system.
Researchers at the Okinawa Institute of Science and Technology have identified a brain mechanism that controls how animals adapt their behaviour when circumstances change.
Japan's OIST has discovered a key brain chemical involved in habit change.
The molecule acts as a reset signal, deactivating consolidated behavioural patterns.
The finding could advance treatments for addiction and obsessive-compulsive disorders.
The idea of a giant hidden planet at the edge of the Solar System has surfaced repeatedly for over a century — and fresh data puts it in doubt once more.
The Planet 9 hypothesis predates the 1930 discovery of Pluto.
Unusual orbits of trans-Neptunian objects point to an unseen gravitational source.
New findings suggest the anomalies may be explained without an extra planet.
