Astronomy News with The Cosmic Companion Podcast February 18, 2020

In this week's episode of Astronomy News with The Cosmic Companion, we meet the first European space telescope designed to study the Sun, and a massive young world is found in our galactic neighborhood. We also take a look up at Betelgeuse as one of the most familiar stars in the night sky may be preparing to explode, and we examine an odd radio signal from space which repeats every 16 days, leaving astronomers baffled.<br/><br/>I also interview Dr. Gillian Wilson of the University of California, Riverside about her discovery of XMM-2599, a galaxy that lived fast and died young in the early Universe. Full interview in podcast only. <br/><br/>Video version of this podcast:<br/><br/>On February 10, the Solar Orbiter from the European Space Agency lifted off from Cape Canaveral on a mission to explore the Sun. This vehicle carries 10 instruments, each designed to study a different characteristic of our parent star. This is Europe's first mission to the Sun, and the spacecraft will work with NASA's Parker Solar Probe, attempting to understand solar activity which produces space weather that can affect Earth.<br/><br/>A massive young planet has been discovered by astronomers just 330 light years from Earth. This world, known as 2MASS 1155–7919 b, is roughly 10 times larger than Jupiter, and orbits its parent star at a distance 600 times greater than the distance between the Earth and Sun. Just a handful of planets this size are known to astronomers, and this world is the closest yet found to our home world.<br/><br/>On February 25th, I will interview Annie Dickson Vandevelde of the Rochester Institute of Technology about her discovery of this unusual planet. Listen to this full interview next week on the Astronomy News with the Cosmic Companion podcast.<br/><br/>For several months, the normally bright star, Betelgeuse, seen in the constellation of Orion, has been noticeably dimming. This has led many astronomers, both professional and amateur, to speculate that this massive red giant star may be about to explode as a
