Chandrasekhar: He knew how the stars will die

Chandrasekhar became famous for his discoveries about the evolution of the stars. His work was vast, and he began early, developing his theory of stars’ evolution before he had even turned 20. Google is changing its logo globally to a doodle of him and the Chandrasekhar Limit. That refers to his calculation that once a star reaches 1.44 times the size of our own sun, it doesn’t form a white dwarf as expected but collapses, eventually becoming a black hole.

ISRO launched 104 satellites in one mission

India has created history today by successfully launching 104 satellites on a single mission, overtaking the previous record for most spacecraft launched at a single attempt, which currently stands at the thirty-eight orbited by Russia’s Dnepr in June 2014, of which thirty-two were deployed from the rocket itself while a thirty-third failed to separate. Salute to ISRO scientists!

Solstice & Strawberry Moon tonight

Today, the summer solstice and full moon coincide — a rare event, indeed, that hasn’t happened in nearly 70 years, according to The Old Farmer’s Almanac. It’s a once-in-a-generation pairing: the start of astronomical summer and emergence of the full “Strawberry Moon.” June’s full Strawberry Moon got its name because the native American Algonquin tribes knew it as a signal to gather ripening strawberry fruit.
