A team of astronomers used data from both the NASA/ESA Hubble Space Telescope and ESA's Gaia satellite to directly measure the 3D motions of individual stars in a nearby galaxy. The achieved accuracy is better than anything previously measured for a galaxy beyond the Milky Way.

Could 2,000 years of belief be wrong? Are we in fact living on a disc rather than a globe? One believer from the Flat Earth Society is determined to find out. 'Mad' Mike Hughes is all set to build his own rocket to see for himself that the Earth is flat.

Read moreHeavy nitrogen molecules reveal planetary-scale tug-of-war
Nature whispers its stories in a faint molecular language, and scientists can finally tell one of those stories this week, thanks to a one-of-a-kind instrument that allowed them to hear what the atmosphere is saying with rare nitrogen molecules.

With a miniaturised space probe capable of being accelerated to a quarter of the speed of light, we could reach Alpha Centauri, our nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past.

Read moreNearby pulsars shed light on the antimatter puzzle
There are too many high-energy positrons in the cosmic rays reaching the Earth. These positrons could be being produced by pulsars in our vicinity. The most recent measurements have practically excluded this possibility, strengthening the competing and much more exotic hypothesis concerning the origin of the excess positrons.

Read moreContracting white dwarf observed for the first time
Astrophysicists have found the first observational evidence for a contracting white dwarf. Constant high spin-up rate of a star of this type, located in an enigmatic binary system, can be easily explained if the white dwarf is contracting.

Read moreWinds blowing off a dying star
Stars like our Sun eject large amounts of gas and dust into space, containing various elements and compounds. Asymptotic giant branch -- AGB -- phase stars, near their end of life, are particularly significant sources of such substances in our galaxy.
