Eclipses come in many forms
Eclipses are one of nature’s most awesome spectacles, and scientists have learned a lot by observing them and related celestial alignments — occultations and transits.

A new, nonexplosive source of black holes?
At least one black hole may have formed from the collapse of a cloud of gas, which is not the usual birthing scheme. This might even be how some of the earliest gargantuan black holes developed.
