Messier 57 (2021)
- Constellation: Lyra
- Right Ascension: 18h 53m 35.079s
- Declination: +33° 01′ 45.03″
- Distance: 2,567 ly
Messier 57 is a planetary nebula located in Lyra. A planetary nebula when a star nears the end of its life at the end of its red giant phase, the outer layers are blown off as the star shrinks down to be come a white dwarf. The exposed core of the star ionizes the surrounding gas causing it to glow. Planetary nebula typically only last a few ten thousands of years as the gas dissipates.
The blueish-green light comes from ionized oxygen, and the red outer layers come from ionized hydrogen. In deeper images it can be seen extending out much further. The central star shines at magnitude 14.8

Messier 1
- Constellation: Taurus
- Right Ascension: 05h 34m 31.94s
- Declination: +22° 00′ 52.2″
- Distance: 6,500 ly
Messier 1 or the Crab Nebula, a supernova remnant from a star that went supernova in 1054 observed and recorded by Chinese astronomers. Being so bright, it was even visible in the day time. All that remains of the star is a neutron star that spins at 30 times a second that emits pulses of radiation. Such stars are called pulsars as the beam from their magnetic poles causes a pulse of radiation as they rotate. The expanding nebula is illuminated by the radiation outpouring from the pulsar and is expanding at the rate of 1,500 km/s.

NGC 7822 (2020)
- Constellation: Cepheus
- Right Ascension: 00h 01m 08.58s
- Declination: +67° 25′ 17.0″
- Distance: 2,900 ly
Image of part of an young emission nebula that spans 40 light years across located in Cepheus. The cluster is mostly illuminated by a star named BD+66, one of the hottest stars at 100,000 times more luminous than our sun. A young stellar nursery that is forming new stars from the clouds of dust and gas.
