Gravity

If you've ever wondered what would happen to wine aged for a year in space then wonder no more. The first ever tasting of "space wine" has been conducted, with one expert describing it as “more evolved” than its similarly aged earthbound counterpart.

In January scientists reported the detection of very low-frequency gravitational waves. Now astrophysicists have investigated two possible sources – the universe cooling down after the Big Bang, and a field of particles that could be dark matter.

Perhaps surprisingly, gravity is the weakest of the four fundamental forces and the hardest to measure here on Earth. Now, physicists in Austria have made the smallest measurement of gravity so far, equivalent to the gravitational pull of a ladybug.

Dark matter is currently the most widely accepted hypothesis for explaining some of the weirdness we see in the cosmos. But now astronomers have discovered evidence in over 150 galaxies for a long-standing alternative model of “modified gravity.”

Astronomers are a step closer to solving a cosmic mystery, thanks to new Hubble data. Observations show a dwarf galaxy previously found to be missing most of its dark matter is being stripped and slowly torn apart by a larger nearby galaxy.

Scientists have so far been unable to detect dark matter. But a new detector design, using an array of billions of tiny pendulums, could finally break the silence by searching for the effects of dark matter’s incredibly strong gravitational pull.

New findings from NASA's OSIRIS-REx probe of asteroid Bennu's gravity field suggest that the core is less dense than the outside shell, and possibly contains a large void – which could spell its doom in the not-too-distant future.

A Scottish company called Gravitricity has now broken ground on a demonstrator facility for a creative new system that stores energy in the form of “gravity” by lifting and dropping huge weights.

Almost 30 years of observations has revealed that a star in the center of the galaxy orbits the supermassive black hole Sagittarius A* in a rosette, or spirograph shape. The find once again confirms a prediction made by Einstein’s General Relativity.

The Hubble Space Telescope has treated us to another spectacular view of two enormous galaxies locked in a cosmic embrace. The image shows an early stage of a galactic encounter, and the chaotic effect that gravity can have on a grand scale

All sorts of health problems arise when as you take humans out into space. New microgravity simulations show that our guts can become “leaky” after a stint in space, increasing the chances of certain infections and diseases for weeks afterwards.

A new analytical tool suggests distinct microbiome changes caused by spaceflight are most likely caused by microgravity.
