Astronomers Detect Comets Outside our Solar System
Astronomers from The University of Texas at Austin, working with scientists from other institutions and amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star 800 light years from Earth.

Stargazing Summary
One of the most popular stories from ancient mythology is told in a group of constellations that highlight November's sky. Cassiopeia, the vain queen of Ethiopia, claimed that she was the most beautiful woman of all, angering the sea nymphs. They convinced the sea god Neptune to send Cetus, a nasty sea monster, to destroy the kingdom. To appease the gods, King Cepheus ordered his daughter, the princess Andromeda, chained at the edge of the sea as a sacrifice. But she was rescued by Perseus, who flashed the monstrous head of Medusa at Cetus, turning him to stone. Five of these characters stretch from north to southeast in the evening sky.

Hubble's First View
Edwin Hubble takes a peek through the 100-inch telescope at Mount Wilson Observatory in California, which took its first look at the universe on November 2, 1917. Hubble used the telescope to discover that the universe extends far beyond the bounds of the Milky Way Galaxy, and that the universe is expanding. Astronomers and guests will commemorate the telescope's centennial this week. [Mount Wilson Observatory]
Radio Program Highlights
If you want to start hearing the StarDate program in your area, you can request a station to carry our program by emailing the request to stations@stardate.org.
November 1-5: First light. One of the most important telescopes in the history of astronomy took its first peek at the stars a century ago this week, and we'll have details. We'll also talk about the leading light of the hero and much more.
November 6-12: Catching ghosts. The particles known as neutrinos zip through everything. Yet astronomers want to catch them because they tell us a lot about the stars. We'll talk about these ghostly particles and a new effort to catch them, plus much more.
November 13-19: Migrations. Some migrations here on Earth are triggered by the phase of the Moon. And some migrations in a distant galaxy cluster are triggered by close encounters between star clusters. Join us for migrations and more.
November 20-26: Extreme life. Life on Earth can survive in the most unlikely of places, which has implications for life on other planets. Join us for extremophiles, plus probes of the early universe, the first known star cluster, and more.
November 27-December 3: Pulsars. When a massive star dies, it can leave a crushed corpse known as a neutron star. Some of these objects spin rapidly, creating flashes of energy like cosmic lighthouses. Join us for pulsars and much more.
