M15 - Globular Cluster - Deep Sky Videos

Astonomers have found the the super massive black hole at the center of spiral galaxies is always about one percent of the mass of the galaxy's central bulge. They are now interested in determining if this the relationship applies to globular clusters, such as Messier 15, which resemble galactic bulges. In other words, are globular clusters tiny galaxies?

An introduction to the Hertzsprung-Russell diagram.

Feb 24, 2012

M30 - More & More & More Stars - Deep Sky Videos

As globular clusters age they evolve leading to a phenomenon called core collapse. Messier 30 seems to be well into this process.

Mar 04, 2012

M33 - Triangulum Galaxy - Deep Sky Videos

The Tirangulum galaxy, Messier 33, is a spiral galaxy with no central bulge. Astonomers believe that such galaxies do not have a central super massive black hole and have absorbed few if any small galaxies.

Mar 07, 2012

M66 - Deformed Spiral Galaxy - Deep Sky Videos

Spiral Galaxy Messier 65 recently encountered another galaxy causing one of its spiral arms to partially disappear by falling into the galactic center.

Mar 12, 2012

M104 - Sombrero Galaxy - Deep Sky Videos

The Messier 104 was the first 'nebula' Melvin Slipher examined to determine how fast it is moving. He found it is moving away far too fast to be part of the Milky Way.

Mar 22, 2012

Astonomers have identified a red star in a Hubble Space Telescope image that generated the 2012 supernova in Messier 95.

Mar 27, 2012

M13 - Alien Life - Deep Sky Videos

In 1974 Human Kind used the Aracebo radio telescope to send a message to the Hercules globular cluster. With luck we'll hear and answer in about 50,000 years. But it's unlikely because globular clusters are not good place to live.

Mar 29, 2012

M83 - Southern Pinwheel Galaxy - Deep Sky Videos

Several supernovae in Messier 83 in the past hundred years indicate it is one of the most active star forming galaxies nearby.

Apr 01, 2012

M40 - Double Star - Deep Sky Videos

Unlike the fuzzy objects in Messier's catalog, Messier 40 is pair of stars that aren't even a binary. So does the object belong in the catalog? Well, that was Messier's decision.

Apr 08, 2012

M53- Which way is up in space? - Deep Sky Videos

Up and down are meaningful on Earth but make little sense in space. But what about North and south? How do astronomers determine direction?

Apr 11, 2012

M27 - Dumbbell Nebula and Biscuits - Deep Sky Videos

May 13, 2012

M56 - Old & Not That Exciting - Deep Sky Videos

Messier 56 is little studied globular cluster because it's difficult to observe being close to the galactic plane and one of the most distant. But it is known to be one of the oldest globular clusters, nearly as old as the Milky Way.

May 15, 2012

M92 - Rare Earths in a Globular Cluster - Deep Sky Videos

Paul shares a photo of comet Garradd, that happened to be near Messier 92, to show how much they look alike and why comet hunter Charles Messier was so annoyed by these nebulae that he cataloged all those he saw.

May 16, 2012

M77 - A Special Kind of Galaxy - Deep Sky Videos

Messier 77 is a Seyfert galaxy meaning it has an active galactic nucleus with a large cloud of hot gas being absorbed by the central super massive black hole. That places it between the Milky Way with a mostly dormant nucleus and a quasar with an extremely active nucleus.

May 24, 2012

M110 - Andromeda's Companion - Deep Sky Videos

M110 is a dwarf elliptical galaxy left over from the formation of M31 Andromeda galaxy which it now orbits. It is a late addition to the Messier catalog as Messier discovered it but didn't specifically catalog it.

May 28, 2012

M4 - White Dwarfs - Deep Sky Videos

Messiers 4 is a nearby globular cluster of very old stars many of which are white dwarfs. The dwarfs' were individually resolved by the Hubble Spce telescope and the oldest dated to about 12 billion years, consistent with the age of the universe.

Jun 02, 2012

Smashing into Andromeda (NEWS) - Deep Sky Videos

The first ever measurement of the proper motion of the Andromeda galaxy confirmed it is heading for a collision with the Mily Way in about four billion years.

Jun 06, 2012

M101 - Supernova and Pinwheel Galaxy - Deep Sky Videos

The Pinwheel galaxy, M101, is a jumble of spiral arms thought to be produced by stars formed by compression waves propagating around the galaxy. It is also the site of the most recent type 1a supernova.

Jun 10, 2012

M45 - Seven Sisters or Pleiades - Deep Sky Videos

The Pelieades is an open cluster of stars that is passing through a diffuse cloud and dust to create a reflection nebula visible in long exposure photographs. Although there are about a thousand stars in the cluster the seven brightest are easily visible with the naked eye for now as they will eventually explode as supernovae.

Jun 20, 2012

M37 - Clusters of Stars - Deep Sky Videos

Messier 37 is a typical open cluster of stars. But it is useful for demonstrating how to determine the age of a cluster.

Jul 02, 2012

M35 - Motion of Stars - Deep Sky Videos

Astronomers recorded the positions of the stars in the open cluster Messier 35 for decades to track their motion and from that determine the mass of the cluster. Based on their measurement it does not contain much if any dark matter.

Jul 05, 2012

Most Massive Star in the Universe - Deep Sky Videos

The Tarantula Nebula is an absolutely huge star forming region in the Large Mangellenic Cloud with equally huge brightly burning stars.

Jul 22, 2012

Really, Really Old Spiral Galaxy - Deep Sky Videos

Galacy BX442 is a very old galaxy ten billion light years from earth. It resembles a grand design spiral galaxy but its spectra reveals it is far to turbulent. So the spiral structure is probably due to a passing or nearby companion galaxy.

Jul 24, 2012

M97 - Owl Nebula or a Pokemon - Deep Sky Videos

The Owl nebula is a shell of gas cast off from a star when it evolved into a red giant. This nebula is oriented relative to Earth so the geometry of the gas release is apparent to astronomers.

Jul 29, 2012

M32 - Satellite Galaxy - Deep Sky Videos

Messier 32 is an unusually compact dwarf elliptical galaxy. Astronomers thing it was once a larger spiral galaxy that lost its disk of stars to the Andromeda Galaxy leaving only the core behind.

Aug 20, 2012

M76 - Little Dumbbell Nebula - Deep Sky Videos

The central star of the planetary nebula Messier 76 is quite rare. It is a white dwarf with a surface layer of carbon rather than hydrogen or helium. Apparently after its first expansion phase when it release most of it's remaining hydrogen creating the nebula it contracted and experienced a helium flash converting the helium to carbon and created a second nebula.

Aug 23, 2012

M20 - Trifid Tebula - Deep Sky Videos

The Trifid is a remarkable astronomical object of stars dust and gas because it presents three types of nebula; emission, reflection and absorption.

Aug 28, 2012

Here's a look at how astrophotographs are produced by large modern telescopes and how computers aid in the search for supernovae.

Aug 29, 2012

M31 - Andromeda Galaxy - Deep Sky Videos

The Andromeda Galaxy, Messier 31, shares the title of the largest galaxy in the Local Group with the Milky Way. It was key to astronomers' realization that the universe is larger than the Milky Way.

Sep 03, 2012

M85 - Lenticular Galaxy - Deep Sky Videos

Lenticular galaxies, such as Messier 85, often look like elliptical galaxies to us but they are disk shaped rather than spherical like the ellipticals. They are common in galaxy clusters where spiral galaxies are rare and rare outside the clusters where spirals are common. So astronomers think they are formed when a spiral galaxy encounter the gas cloud of a cluster and has its dust and gas, and hence spiral arms, stripped from it.

Sep 05, 2012

M71 - Star Spotting - Deep Sky Videos

James McCormac explains the stellar transit process and the challenge of finding a transiting exoplanet.

Sep 10, 2012

M96 - Coffee Break Galaxy - Deep Sky Videos

Spiral galaxy Messier 96 is a spiral galaxy that is clearly distorted probably by an interaction with a another large galaxy that passed nearby.

Oct 02, 2012

M67 - Where did the Sun come from? - Deep Sky Videos

The open cluster Messier 67 has been thoroughly studied because it looked liked the best candidate for the location where the star nearest and dearest to our hearts was formed; our sun Sol.

Oct 07, 2012

M57 - Ring Nebula - Deep Sky Videos

The ring nebula was once thought to be a sphere of matter discharged by its central star that was so thin that only the edges were visible. It is now thought to be truly ring shaped and oriented so we see through it from Earth.

Oct 14, 2012

M29 - Pants Cluster - Deep Sky Videos

Messier 104 is an open cluster that is difficult to see due to intervening dust. Absent the dust it would likely be very bright as seen form Earth.

Oct 25, 2012

M22 - Black Hole Clusters - Deep Sky Videos

Mike shares a paper that suggests Messier 22 contains a cluster of black holes around it's center in contract to prevailing theories.

Nov 04, 2012

M65 - An Easy Life - Deep Sky Videos

Spiral galaxy Messiar 65 has been undisturbed in its recent history in contract to it's companion in the Leo Triplet, Messier 66, which has many regions of active star formation.

May 29, 2013

M2 - Recycled Stars - Deep Sky Videos

The traditional theory of globular clusters is that their stars all formed at roughly the same time so stars of the same mass should have the same properties. But a close look at the clusters' color magnitude diagrams reveals most have two, occasionally, three populations of stars likely formed hundreds of millions of years apart. Spectra of certain elements in the stars reinforce the presence of multiple stellar populations.

Aug 20, 2013

Green Flash and Belt of Venus - Deep Sky Videos

Pete Lawrence explains the phenomenon and captures pictures of the green flash.

Dec 05, 2013

Magellanic Clouds (and Apollo 16) - Deep Sky Videos
