-
Object 22: Above and Below or Something Like That
01/06/2020 Duración: 14minNGC 55 has the interesting distinction of being the closest galaxy to Earth that is seen edge-on, and it also contains an ultraminous X-ray source (ULX) uncreatively named NGC 55 ULX.
-
Object 21: Retro Gaming and Star Formation
18/05/2020 Duración: 09minNGC 281, which is also called the Pacman Nebula, is a place where star formation has been triggered two different ways, although the stars are not chased by any Ghost Nebulae.
-
Object 20: A Classic Non-Comet
04/05/2020 Duración: 10minEven though it may be rather ordinary from a scientific standpoint, the open cluster Messier 23 is a very popular with amateur astronomers.
-
Object 19: Probably Not the Y2K Bug
20/04/2020 Duración: 09minEverything about the triple star system V505 Sgr looked normal aside from an abrupt change in the orbits of the stars sometime around the year 2000.

23/03/2020 Duración: 09min4U 1957+115 is a low mass X-ray binary, a binary star system with a normal star about the size of the Sun and a relatively small black hole three times the mass of the Sun, and it also has an unfortunately confusing name.
-
Object 16: Playing Golf on the Moon
09/03/2020 Duración: 13minThe extremely bright, point-like emission from J1955+5131 in visible light and radio waves makes it useful for matching up images from different parts of the electromagnetic spectrum as well as an interesting object in its own right.
-
Object 15: Calibrated Variability
24/02/2020 Duración: 13minDespite the variability of the gamma radiation from J0510+1800, this blazar is used as a flux calibrator at millimeter and submillimeter wavelengths.
