M45 – The Pleiades Cluster

M45 - The Pleiades Cluster

The Pleiades, also known as M45, the Seven Sisters or Subaru (Japan), is an open star cluster containing middle-aged stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.

In celebration of the 17th anniversary of the launch and deployment of NASA’s Hubble Space Telescope, a team of astronomers is releasing one of the largest panoramic images ever taken with Hubble’s cameras. It is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth – and death – is taking place.

Hubble’s view of the nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born.

The immense nebula contains at least a dozen brilliant stars that are roughly estimated to be at least 50 to 100 times the mass of our Sun. The most unique and opulent inhabitant is the star Eta Carinae, at far left. Eta Carinae is in the final stages of its brief and eruptive lifespan, as evidenced by two billowing lobes of gas and dust that presage its upcoming explosion as a titanic supernova.

The fireworks in the Carina region started three million years ago when the nebula’s first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen. Radiation from these stars carved out an expanding bubble of hot gas. The island-like clumps of dark clouds scattered across the nebula are nodules of dust and gas that are resisting being eaten away by photoionization.

The hurricane blast of stellar winds and blistering ultraviolet radiation within the cavity is now compressing the surrounding walls of cold hydrogen. This is triggering a second stage of new star formation.

Our Sun and our solar system may have been born inside such a cosmic crucible 4.6 billion years ago. In looking at the Carina Nebula we are seeing the genesis of star making as it commonly occurs along the dense spiral arms of a galaxy.

The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).

This image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope’s Advanced Camera for Surveys. The Hubble images were taken in the light of neutral hydrogen. Color information was added with data taken at the Cerro Tololo Inter-American Observatory (CTIO) in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

Interesting Hubble Facts

In its 17 years of exploring the heavens, NASA’s Hubble Space Telescope has made nearly 800,000 observations and snapped nearly 500,000 images of more than 25,000 celestial objects. Hubble does not travel to stars, planets and galaxies. It takes pictures of them as it whirls around Earth at 17,500 miles an hour. In its 17-year lifetime, the telescope has made nearly 100,000 trips around our planet. Those trips have racked up plenty of frequent-flier-miles, about 2.4 billion, which is the equivalent of a round trip to Saturn.

The 17 years’ worth of observations has produced more than 30 terabytes of data, equal to about 25 percent of the information stored in the Library of Congress. Each day the orbiting observatory generates about 10 gigabytes of data, enough information to fill the hard drive of a typical home computer in two weeks. The Hubble archive sends about 66 gigabytes of data each day to astronomers throughout the world.

Astronomers using Hubble data have published nearly 7,000 scientific papers, making it one of the most productive scientific instruments ever built.

Pleiades, 50mm, No Tracking, Finger Lakes region of New York

Now that the Milky Way is settling down for the winter, I decided to move on to other subjects on this very clear night. My last few outings have been increasingly plagued by dew forming on my lens. Actually, my entire camera has been dripping wet most nights. So I went to Walmart yesterday and grabbed a few sets of hand-warmers and taped a pair around my lens. They fit perfectly! No need to wipe every 90 seconds. I shot for hours without any dew at all, while my car made puddles around its perimeter.

Because my nifty-fifty gets nasty real quick on any stars that aren’t near dead-center, I had to re-frame the Pleiades every 5 minutes or less. That makes a pretty big difference. I also shot nearly 600 dew-free frames of Andromeda last night. Here’s that:

I used DeepSkyStacker to stack 238 images captured with my Canon 50mm f/1.8 set to f/2.2, 5-seconds, ISO 12800 on a Canon 60D body.

I stretched the output just a bit in Photoshop — only 1-1/2 Levels adjustments — any more brought all the noise back. I was pleased to get this much dust glow without having a background that looked like a rain-soaked end-of-semester sofa sitting at the curb. I tweaked the colors a bit to get some blue back, and then cropped and re-sampled the image 200 percent.

My computer, my drives and my long lens are conspiring to get a cheap tracker for me this Christmas. They’ve had just about enough of these shenanigans.

Pleiades

Pleiades

The Pleiades (M45). This is a shot I’ve been wanting to do for a long time. Previous attempts were unsatisfactory because my 127 Mak has too much focal length for this object and looked straight through it and using a camera lens made unattractive spokes around the stars caused by the iris of the lens. With the 150mm Newtonian scope the framing is pretty much perfect and plenty of nebulosity can be captured. Also the spikes caused by the secondary mirror spider add to the image. Not perfect perhaps but definitely the best attempt so far. This image has been edited sine originally being posted with extra data added and flat files replaced.

[Wikipedia] In astronomy, the Pleiades, or Seven Sisters (Messier 45 or M45), are an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades were probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.[en.wikipedia.org/wiki/Pleiades]

Astronomy (from Greek: αστρονομία) is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernova explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth’s atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole.
Astronomy is the oldest of the natural sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is now often considered to be synonymous with astrophysics.
During the 20th century, the field of professional astronomy split into observational and theoretical branches. Observational astronomy is focused on acquiring data from observations of astronomical objects, which is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena. The two fields complement each other, with theoretical astronomy seeking to explain the observational results and observations being used to confirm theoretical results.
Astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Amateur astronomers have made and contributed to many important astronomical discoveries, such as finding new comets.
