closest look at exploding comet by NASA

Most complete and detailed observation of the formation and dissipation of comet outburst

NASA's exoplanet-tracking satellite Transiting Exoplanet Survey Satellite (TESS) captured a rare glimpse of the entirety of a "comet outburst"-- an epic cosmic event where a comet spontaneously combusts in an intense explosion. This is the most...

Global storms on Mars launch dust towers 80 km (50 miles) into the sky

When a massive dust storm on Mars-- like the one in 2018-- reaches its full potential, it can transform into a globe-bestriding colossus. This happens often on the red planet, and these storms typically start out as a sequence of smaller storms. NASA scientists said...
