The sun as you've never seen it before

Powerful flares, breathtaking views across the solar poles, and a curious solar "hedgehog" are among the haul of spectacular images, movies and data returned by Solar Orbiter from its first close approach to the sun. Although ...

Astronomers take 'heartbeat' of black hole

A black hole gets a large corona before it emits jets. This is revealed, among other things, by the heartbeat graph that an international team of astronomers has made of a black hole and a star orbiting around each other. ...

NASA rocket mission to study the origin of slow solar winds

Study: Scientists carry greater credibility than spiritual gurus

What influence does the source of information have on its credibility? Scientists have more authority than spiritual sources, both among religious and non-religious people. This is apparent from a large-scale experiment conducted ...

New evidence of geologically-recent Venusian volcanism

New data analysis techniques allow evidence of recent volcanism to be found in old Magellan spacecraft data. It is unclear if this activity is occurring today, or if it occurred within tens of million years, but geologically ...

'Campfires' offer clue to solar heating mystery

Computer simulations show that the miniature solar flares nicknamed 'campfires," discovered last year by ESA's Solar Orbiter, are likely driven by a process that may contribute significantly to the heating of the sun's outer ...
