When it comes to exoplanets, the most exciting for many people are, of course, the ones which may be the most Earth-like, since these are regarded as the most likely to possibly support some form […]

Tilted Aquaplanets Might Still be Habitable, Study Suggests

With so many exoplanets now being discovered on a regular basis by astronomers, the focus has turned to what number of them might be habitable for some kind of life. For life as we know it at least, that depends on a number of […]

Dawn Spacecraft Takes Its Best-Yet Image of Dwarf Planet Ceres

The best image of dwarf planet Ceres obtained so far by the Dawn spacecraft, from 740,000 miles (1.2 million kilometers) away. Images will get much better as the spacecraft approaches Ceres over the next few months. Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

The Dawn spacecraft continues to make its way closer to a world which still hasn’t […]

Hot 'Super-Earths' Provide Clues to Water in Exoplanet Atmospheres

The search for exoplanets is about to enter an exciting new phase, as the Transiting Exoplanet Survey Satellite (TESS) mission has now been cleared for development by NASA. TESS will greatly expand the number of stars being observed for evidence of exoplanets […]

Most of the Water In the Solar System Is Older Than the Sun, New Study Suggests

An artist’s concept of the formation process of the Solar System out of an interstellar molecular cloud and its enrichment with water. A recent study has indicated that up to half of Earth’s water is older than the Sun itself, likely originating in that cold molecular cloud that spawned our Solar System. Image credit: […]
