The Habitability of Earth Tells Us the Likelihood of Finding Life Elsewhere
The hunt for habitable worlds has become a hot topic in astronomy. For decades, the search has been focussed on planets in the "Goldilocks zone”; that narrow band around a star where water stays liquid, not too hot to boil away, not too cold to freeze solid. But habitability is far more complex and ruthless than just getting the temperature right. A world needs a protective magnetic field to shield life from radiation, a stable atmosphere thick enough to regulate climate but not so dense it crushes everything beneath it, and the right cocktail of elements forged in the nuclear furnaces of dying stars.
Elevating Europe in space for fifty years
Video: 00:02:46
For half a century, the European Space Agency (ESA) has been serving Europe as its space agency and inspiring its citizens. On 30 May 1975, the ESA Convention was signed by 10 founding Member States and has since now expanded to 23 Member States, three Associate Members, four Cooperating States and a Cooperation Agreement with Canada. This anniversary year provides the opportunity to reflect not only on ESA’s past achievements, but even more so on its future perspectives.
Strange Object is Releasing Regular Blasts of Both X-Rays and Radio Waves
Just when astronomers think they're starting to understand stellar activity, something strange grabs their attention. That's the case with a newly discovered stellar object called ASKAP J1832-0911. It lies about 15,000 light-years from Earth and belongs to a class of stellar objects called "long-period radio transients." That means it emits radio waves that vary in their intensity on a schedule of only 44 minutes per cycle. It does the same thing in X-ray intensities, which is the first time anybody's seen such a thing coupled with long-period radio transits.

Webb Reveals that Europa's Surface is Constantly Changing
You'd think that icy worlds are frozen in time and space because they're - well - icy. However, planetary scientists know that all worlds can and do change, no matter how long it takes. That's true for Europa, one of Jupiter's four largest moons. Recent observations made by the James Webb Space Telescope (JWST) zero in on the Europan surface ices and show they're constantly changing.
