This month, we’ll explore the starry skies of October to see some planets, constellations, and maybe even a comet! Don’t forget to bring along your binoculars or a small telescope to enhance the view. Be sure to dress for the weather, and bring along a pair of binoculars or a small telescope to enhance your view. Carolyn Collins Petersen tells us what’s up in the October 2013 night sky.

Astronomers may have found the densest galaxy in the nearby universe. The galaxy, known as M60-UCD1, is located near a massive elliptical galaxy NGC 4649, also called M60, about 54 million light-years from Earth. This composite image shows M60 and the region around it, where data from NASA’s Chandra X-ray Observatory are pink and data from NASA’s Hubble Space Telescope are red, green, and blue. The Chandra image shows hot gas and double stars containing black holes and neutron stars, and the Hubble image reveals stars in M60 and neighboring galaxies including M60-UCD1. The arrow points to M60-UCD1.
Ten years ago, astronomer John Blakeslee spotted dots of light peppered throughout images of a giant cluster of galaxies, called Abell 1689. Each dot was not one star, but hundreds of thousands of stars crowded together in groupings called globular clusters. Blakeslee counted 500 such clusters, the brightest members of a teeming population of globular clusters.
This image shows an example of a bipolar planetary nebula known as PN Hb 12 — also known as Hubble 12 — in the constellation of Cassiopeia. The striking shape of this nebula, reminiscent of a butterfly or an hourglass, was formed as a Sun-like star approached the end of its life and puffed its outer layers into the surrounding space. For bipolar nebulae, this material is funneled towards the poles of the aging star, creating the distinctive double-lobed structure.
Observations using NASA’s Hubble Space Telescope and the New Technology Telescope have found that bipolar planetary nebulae located towards the central bulge of our Milky Way appear to be strangely aligned in the sky — a surprising result given their varied and chaotic formation.
Astronomers have used ESO’s New Technology Telescope and the NASA/ESA Hubble Space Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned — a surprising result given their different histories and varied properties.
Join your Host Carolyn Collins Petersen for a look at September’s night sky viewing. A night time show available to all and of course we wish you clear skies.
This unprecedented image of Herbig-Haro object HH 46/47 combines radio observations acquired with the Atacama Large Millimeter/submillimeter Array (ALMA) with much shorter wavelength visible light observations from ESO’s New Technology Telescope (NTT). The ALMA observations (orange and green, lower right) of the newborn star reveal a large energetic jet moving away from us, which in the visible is hidden by dust and gas. To the left (in pink and purple) the visible part of the jet is seen, streaming partly towards us.
Keck’s Cosmic Video Summer School Series – Mergers and Acquisitions by the Andromeda Galaxy as Documented by Keck
Raja Guhathakurta, of the University of California at Santa Cruz, has a deep passion for advancing astronomy research and education. A professor in one of America’s finest astronomy programs, Raja makes complex and technical details of the cosmos intimate and understandable with humor, striking images and beautiful computer animations.
In this week’s installment of Keck’s Cosmic Summer School, Professor Guhathakurta presents ground breaking research into the nature and evolution of the Andromeda Galaxy, M31, our closest neighbor in the vast expanse of the Universe and explains how studying the “Galaxy Next Door” offers many keys to knowing our own Milky Way home.
This is now the 11th in a series of talks that you can view for free other video talks include Nobel Worthy: The Accelerating Expansion of the Universe, Keck and the Outer Solar System, Discovering New Worlds with Keck. Visit Keck via the link here and enjoy the talks images and computer animations.
Hubble explores the origins of modern galaxies – Astronomers see true shapes of galaxies 11 billion years back in time
Astronomers have used observations from Hubble’s CANDELS survey to explore the sizes, shapes, and colours of distant galaxies over the last 80% of the Universe’s history. In the Universe today galaxies come in a variety of different forms, and are classified via a system known as the Hubble Sequence — and it turns out that this sequence was already in place as early as 11 billion years ago.
