Red dwarfs may be more hazardous to one’s health than previously thought

30 October 2020 Astronomy Now

Observations of Barnard’s Star, a nearby red dwarf, suggest planets orbiting the galaxy’s most commonplace stars may be challenging for life.

Study shows Venus may have once enjoyed a temperate climate

23 September 2019 Astronomy Now

Computer simulations indicate Venus may have been a temperate, possibly habitable, planet for two to three billion years before evolving into the hellish hothouse seen today.

“Electric wind” can strip Earth-like planets of oceans and atmospheres

21 June 2016 Astronomy Now

The space environment around a planet plays a key role in determining what molecules exist in the atmosphere – and whether the planet is habitable for life. New research shows that Venus has an “electric wind” strong enough to remove the components of water from its upper atmosphere, which may have played a significant role in stripping Earth’s twin planet of its oceans.

Stifling atmospheres could limit number of habitable exoplanets

26 May 2016 Astronomy Now

New research reveals that fewer than predicted planets may be capable of harbouring life because their atmospheres keep them too hot. Computer simulations show that planets similar to or larger in mass than the Earth that are born with thick envelopes of hydrogen and helium are likely to retain their stifling atmospheres.
