The Golden Standard

2024/02/19

The Type Ia supernova SN 2005cf was observed at multiple wavelengths for three months after its appearance, allowing astronomers to create templates of its spectrum that could be used to measure distances to other Type Ia supernovae.

No Shockingly Dumb Jokes in This Episode

2024/02/05

Kappa Cassiopeiae is a large blue variaable star that is most potentially interesting because of the bow shock between its stellar winds and the interstellar medium.

The Really Really High Expectations Exoplanetary System

2024/01/22

47 Ursa Majoris is a nearby Sun-like star that astronomers have intensely studied in an effort to find an Earth-like exoplanet, and while three exoplanets have been found orbiting the star, none of them are remotely similar to the Earth.

Oyster?

While the planetary nebula NGC 1501 is a popular amateur astronomy target, the newly formed, hot, pulsating white dwarf at its center is much more interesting to professional astronomers.

George's 2020 Data Processing Project from Hell

2023/12/25

As the second closest spiral galaxy to the Milky Way, Messier 33 has been a very popular observing target for both amateur and professional astronomers, and even I have made images of the galaxy.

The Mystery Spot

2023/12/11

The white dwarf GD 394 seems to have an abnormal amount of heavy elements in its outer atmosphere and also varies in brightness with a period of 1.146 days, and no one understands why.

Imagine Marilyn Monroe in a Movie Named the Great Attractor

A Water World without Kevin Costner

2023/10/16

The Kepler-138 star system contains at least four exoplanets, one of which may be a "water world" covered in a very deep ocean.

Objects in the Mirror May Be More Complicated Than They Appear

2023/10/02

The protostellar object PDS 70 has a very complicated protoplanetary system that includes a disk of gas and dust and two protoexoplanets.

The Red Rectangle
