My first Astro image. I took this photo of the dumbbell nebula last night up in our observatory. The Dumbbell Nebula (Messier 27/M27) is about 1,360 light years away and has a diameter of 1.44 light years. It lies in the Vulpeca constellation. What you're seeing are the gaseous remnants from a star which had reached the end of its life cycle. What happens when stars can no longer contain themselves and run out of nuclear fuel is that they expel hydrogen, helium, oxygen, and sometimes heavier elements. This particular photo was taken through an hα (h-alpha) filter, but LMR, OIII, SII, and Hα were all used. Through the hα filter, the brightness that you're seeing is hydrogen. Processed images to come soon! Excited to learn digital processing on top of my art and Photoshop skills. #nebula#dumbbellnebula#messier27#ncg6853#physics#astronomy#science#photography
....شاید پا هام روی این سیاره خاکی باشه، اما بین ستاره ها سفر می کنم. گاهی به نزدیکی مریخ می رم، گاهی از بین کمربند سیارکی عبور می کنم و به مشتری می رسم و گاهی به مرز های منظومه شمسی و فراتر از اون. البته من بیشتر به سه دقیقه اول عالم سفر می کنم. ...امروز تا نزدیکی های مشتری رفتم. شاید کمی هم دور تر....

فردایی بهتر را به تمام ما عطا کن.
به حق تمام مهربانی هایت مگذار امشب هم کسی در حسرت یک تکه نان به خواب برود...
به تمام بخشندگی هایت مگذار کسی با ناراحتی شب خود را به صبح برساند...

Whenever I gaze up at the moon, I feel like I'm on a time machine. I am back to that precious pinpoint of time, standing on the foreboding - yet beautiful - Sea of Tranquility. I could see our shining blue planet Earch poised in the darkness of space. Buzz Aldrin
2 days + 2 Aggie Star Parties = free fun for all ages! Join Texas A&M Astronomy tonight (Wednesday) from 9-11 p.m. on campus at the Simpson Drill Field Review Stand, then head west for tomorrow’s (Thursday) kickoff event in a new quarterly series of Star Parties at The Stella Hotel! Hear more on the latter from Texas A&M astronomer Jennifer Marshall and her students, courtesy of KBTX’s “Brazos Valley This Morning” segment: http://tx.ag/KBTXstella #tamu#astronomy#thestellahotel#stargazing#nature#texas#keeplookingup#BeCurious
Our eclipse glasses are in! Marsha, Paige and Dr. Engle tried them out at our #springhill locationand give their approval! You can come and get a pair for only $1! Remember you MUST keep the glasses on the entire time unless you a in an area that will experience totality (the moon COMPLETELY blocking the sun) and then only for a short time will it be safe to remove your glasses. Don't miss the Great American #eclipse August 21st. Look up where you need to be and when for more info! Happy eclipsing!! #youonlygettwo#eyesafety#space#totality#astronomy#bowtie#eyedoctor#eyes#vision

It's unlikely that I travel to Mars in my lifetime. But for now the Atacama Desert in Chile is as similar to Mars as I can wish for! One of the driest places on our planet, where the sky touches the Earth. Photographed from a dry stream with light of the rising moon. Atacama is also known for its stunning night sky. The Milky Way with the Southern Cross and bright stars Alpha & Beta Centauri appear in this view.

The Hubble telescope reveals a rainbow of colours in this dying star, called IC 4406. Like many other so-called planetary nebulae, IC 4406 exhibits a high degree of symmetry. The nebula's left and right halves are nearly mirror images of the other. If we could fly around IC 4406 in a spaceship, we would see that the gas and dust form a vast donut of material streaming outward from the dying star. We don't see the donut shape in this photograph because we are viewing IC 4406 from the Earth-orbiting Hubble telescope. From this vantage point, we are seeing the side of the donut.
This side view allows us to see the intricate tendrils of material that have been compared to the eye's retina. In fact, IC 4406 is dubbed the 'Retina Nebula.'#astronomy#hubblespacetelescopeseria#hubblespace#nasa#science#nebula
This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what's eating it. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this "wanna-be" star and sculpting the gas and dust into its long shape.
The culprits are 65 of the hottest, brightest known stars, classified as O-type stars, located 15 light-years away from the knot, towards the right edge of the image. These stars, along with 500 less bright, but still highly luminous, B-type stars make up what is called the Cygnus OB2 association. Collectively, the association is thought to have a mass more than 30 000 times that of our Sun.
The caterpillar-shaped knot, called IRAS 20324+4057, is a protostar in a very early evolutionary stage. It is still in the process of collecting material from an envelope of gas surrounding it. However, that envelope is being eroded by the radiation from Cygnus OB2. Protostars in this region should eventually become young stars with final masses about one to ten times that of our Sun, but if the eroding radiation from the nearby bright stars destroys the gas envelope before the protostars finish collecting mass, their final masses may be reduced.
Spectroscopic observations of the central star within IRAS 20324+4057 show that it is still collecting material quite heavily from its outer envelope, hoping to bulk up. Only time will tell if the formed star will be a "heavy-weight" or a "light-weight" with respect to its mass.
This image of IRAS 20324+4057 is a composite of Hubble Advanced Camera for Surveys (ACS) data taken in green and infrared light in 2006, and ground-based hydrogen data from the Isaac Newton Telescope in 2003, as part of the IPHAS H-alpha survey. The object lies 4500 light-years away in the constellation of Cygnus (The Swan).#astronomy#hubblespacetelescopeseria#hubblespace#science#nasa
This composite image is a view of the colorful Helix Nebula taken with the Advanced Camera for Surveys aboard NASA/ESA Hubble Space Telescope and the Mosaic II Camera on the 4-meter telescope at Cerro Tololo Inter-American Observatory in Chile. The object is so large that both telescopes were needed to capture a complete view. The Helix is a planetary nebula, the glowing gaseous envelope expelled by a dying, sun-like star. The Helix resembles a simple doughnut as seen from Earth. But looks can be deceiving. New evidence suggests that the Helix consists of two gaseous disks nearly perpendicular to each other.#astronomy#hubblespacetelescopeseria#hubblespace#nasa#science#astronomy
