A Quick Look at the Sagittarius A Black Hole Swarm
Astronomers have found evidence for a new bounty of black holes at the center of the Milky Way. These are stellar-mass black holes that typically weigh between five to 30 times the mass of the Sun.
Researchers combed through data from NASA's Chandra X-ray Observatory to look for possible black holes in close orbit with a star. They found about a dozen strong black hole candidates within a very short distance of the supermassive black hole at the Galactic Center.
This implies the presence of up to a thousand stellar-mass black holes that are also present, but were undetected.

Eagle Nebula: A Quick Look | NASA Chandra
July 16, 2018: New stars form in clusters containing large amounts of dust and gas, including structures like the Pillars of Creation. A newly forming star is located near the tip of the largest Pillar.
The atmospheres of young stars produce X-ray emission, and disks of dust and gas surrounding many of them produce infrared light. Astronomers combine X-ray and infrared data to study the behavior of young stars.
X-ray activity in young stars with disks is, on average, a few times less intense that in young stars without disks.

|| Chandra Darshana - Askganesha ||
#Amavasya which literally translates to ‘new #moon night’ is a very auspicious day in Hinduism and an optimal day to pray for salvation. The moon which appears after Amavasya is called the new moon, observing this moon is known as #Chandra #Darshan.

Symbiotic R Aquarii Star System | Hubble
You can see it change in brightness with just binoculars over the course of a year. Variable star R Aquarii is actually an interacting binary star system, two stars that seem to have a close, symbiotic relationship. About 710 light years away, this intriguing system consists of a cool red giant star and hot, dense white dwarf star in mutual orbit around their common center of mass. The binary system's visible light is dominated by the red giant, itself a Mira-type long period variable star. But material in the cool giant star's extended envelope is pulled by gravity onto the surface of the smaller, denser white dwarf, eventually triggering a thermonuclear explosion and blasting material into space. The featured image from the Hubble Space Telescope shows the still-expanding ring of debris which spans less than a light year and originated from a blast that would have been seen in the early 1770s. The evolution of less understood energetic events producing high energy emission in the R Aquarii system has been monitored since 2000 using Chandra X-ray Observatory data.
