The European Space Agency has released an audio-visual representation of solar activity over the last three years, using data from the Solar Orbiter probe.

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.

China's Chang'e 7 moon-landing mission will apparently include a flag that can flutter in the moon's thin and tenuous atmosphere.

Astronomers are now confident the Event Horizon Telescope can help them decode elusive origins of black hole jets.
