Object 18: 0.2 Seconds of Gamma Rays
06/04/2020 Duración: 07minThe short gamma ray burst GRB 100206A was found in a luminous infrared galaxy, which is very unusual place to find such gamma ray bursts.
-
Object 17: Confusing U
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.
-
Object 14: Exoplanetary Acronym 103b
10/02/2020 Duración: 10minWASP-103 has an acronym for a name and also has a gaseous planet orbiting so close to it that the planet is in danger of being destroyed.
-
Object 13: White Dwarf Facial Reconstruction
27/01/2020 Duración: 07minBV Centaurus is an unusual example of a class of U Gem cataclysmic variable stars in which a white dwarf is stripping gas from a companion star.
-
Object 12: Watching Infrared Paint Dry
13/01/2020 Duración: 11minELAIS N1 is a extragalactic deep field selected specifically for identifying many distant, faint galaxies at infrared wavelengths.
-
Object 11: Howling Fast Differential Rotation
30/12/2019 Duración: 09minPsi Capricorni was the first star other than the Sun where the phenomenon of differental rotation was ever measured.
-
Object 10: Ram Your Jellyfish
16/12/2019 Duración: 11minAbell 85 is a large, nearby cluster of galaxies with so many things happening inside that it could be called a ball of chaos.
-
Object 9: A Cruise Holiday with a Peculiar Carbon Star
02/12/2019 Duración: 09minThe star HD 214714 contains not only a large amount of carbon in its stellar atmosphere but also a peculiar combination of other heavy elements as well.
-
Object 8: A Misbehaving LIRG
18/11/2019 Duración: 10minII Zw 96 is a luminous infrared galaxy (LIRG) where most of the infrared emission comes from some type of off-center region, which is weird compared to most other LIRGs.
-
Object 7: Circles within Circles
04/11/2019 Duración: 11min30 Ari contains four stars and an exoplanet all arranged in a rather complex set of nested orbits.
-
Object 6: Extra Peculiar
21/10/2019 Duración: 08minHD 98851 is both an Am chemically peculiar star and a delta Scuti variable star, and it has two different pulsation cycles, which makes it really peculiar.
-
Object 5: Some Unexpected Helium
07/10/2019 Duración: 10minRV Octantis would be considered a run-of-the-mill RR Lyrae variable star if it wasn't for the unexpected discovery of helium in its atmosphere.
-
Object 4: A Damp Lyman Alpha Elephant
23/09/2019 Duración: 13minThe most interesting thing about the quasar LBSQ 0058+0155 is not the quasar itself but the galaxy between the quasar and Earth.
-
Object 3: Room Temperature
09/09/2019 Duración: 08minHD 85512 is a nearby star slightly smaller and more orange than the Sun. It happens to have an exoplanet that could be close to Earth-like.
-
Object 2: Variable Variability
26/08/2019 Duración: 09minHS Hydrae is a variable eclipsing binary star, which sounds more unusual than it actually is. However, it's precessing, which is not only unusual but also causes the variability to vary over time.
-
Object 1: Not the Pope
12/08/2019 Duración: 08minThe Leo IV Dwarf Galaxy is one of several ultra faint dwarf galaxies that orbit the Milky Way. Galaxies like this are weird relics of when the universe first formed; they contain very old stellar populations and abnormally large amounts of dark matter.
