Comet Leonard
https://spaceweather.com/
Comet Leonard's magnificent tail is braided with multiple filaments of gas and dust. These were created by a series of outbursts that began on Dec. 15th. Two and perhaps three explosions in the comet's core sent streamers of debris billowing down the tail.
The same outbursts boosted the comet's brightness. It is now shining like a 4th magnitude star in the constellation Microscopium, an easy target for small telescopes in the southern hemisphere.
More outbursts are in the offing. The comet is heading for its closest approach to the sun (0.61 AU) on Jan. 3rd. Increasing heat could liberate new jets of gas and dust and maybe even blow away huge chunks of ice and rock. Stay tuned!
