We summarize the week's scientific breakthroughs every Thursday.
The map, spanning 4,000 light-years from the sun in all directions, combines a chart of space dust with the effects of a rare type of young, hot star.
The methane gas may constitute a rarefied atmosphere, or it may come from erupting plumes on Makemake’s surface.
Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.
Building blocks of life have been found on this moon of Saturn. They may come from chemical reactions beyond Enceladus’ possible life-supporting ocean.
The Big Bang may have spawned these theoretical black holes, whose lives are thought to end in a burst of extremely energetic particles.
At just 25, Cecilia Payne-Gaposchkin applied quantum physics to a treasure trove of astronomical observations to show that stars are mostly hydrogen and helium.
Asteroid impacts, microbes, mining: These are a few tactics engineers might one day use to create an Earthlike atmosphere on Mars.
Gravitational waves emitted after two black holes coalesced agree with theories from physicists Stephen Hawking and Roy Kerr.
NASA’s InSight lander listened to Marsquakes for four years. The tremors revealed that Mars may have a solid inner core.
