Cassini looked on last month as methane clouds floated above Ligeia Mare, a big hydrocarbon sea near Titan's north pole. Few clouds had been seen on Titan since 2010, so researchers are trying to gauge the significance of the new observations.

Launched on a sounding rocket to ~200,000ft., NASA's Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS) observed superheated material (10M°K) consistent only with theoretical “nanoflares,” which quickly cool to the corona’s ~2M° average.

Black holes may have grown incredibly rapidly in the newborn universe, perhaps helping explain why they appear so early in cosmic history. Early black hole may have sucked matter in from all around, rather than just from an accretion disk.
