29 Astonishing Images NASA Shared Recently!


Each day NASA posts a different image or photograph on its 'Astronomy Picture of the Day Archive,' featuring our fascinating universe, along with a brief explanation written by a professional astronomer. We decided to gather the best images shared in the month of October. Enjoy!

1. Rosetta's Farewell

After closely following comet 67P/Churyumov-Gerasimenko for 786 days as it rounded the Sun, the Rosetta spacecraft's controlled impact with the comet's surface was confirmed by the loss of signal from the spacecraft on September 30, 2016. One of the images taken during its final descent, this high-resolution view looks across the comet's stark landscape.

2. Aurora Over White Dome Geyser

3. Nest Of The Eagle Nebula

What surrounds the famous Eagle Nebula? The inside of the Eagle Nebula contains eggs -- evaporating gaseous globules -- that typically reside in tremendous pillars of gas and dust and where stars form. This image, though, dramatically captures the area surrounding the Eagle Nebula, showing not only the entire Eagle shape but also enormous volumes of glowing gas and dark dust.

4. A Crumbling Layered Butte On Mars

Pictured is a recently assembled mosaic image of one of the last of the buttes passed by Curiosity on its way up Mt. Sharp -- but also one of the most visually spectacular. Ancient water-deposited layers in relatively dense -- but now dried out and crumbling -- windblown sandstone tops the 16-feet tall structure. The rim of Gale crater is visible in the distance.

5. Trifid, Lagoon, and Mars

Bright nebulae and star clusters along this 5-degree wide field of view are popular stops on telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. Cataloged by 18th-century French astronomer Charles Messier, M20, the colorful Trifid Nebula, and M8, the expansive Lagoon Nebula, are at upper left and center. Both are well-known star-forming regions about 5,000 light-years distant.

6. The Hydrogen Clouds of M33

Gorgeous spiral galaxy M33 seems to have more than its fair share of glowing hydrogen gas. A prominent member of the local group of galaxies, M33 is also known as the Triangulum Galaxy and lies about 3 million light-years distant. The galaxy's inner 30,000 light-years or so are shown in this telescopic portrait that enhances its reddish ionized hydrogen clouds or HII regions.

7. Moon, Mercury, and Twilight Radio

8. Hurricane Ivan from the Space Station

Ninety-percent of the houses in Grenada were damaged by the destructive force of Hurricane Ivan. At its peak in 2004, Ivan was a Category 5 hurricane, the highest power category on the Saffir-Simpson Scale, and created sustained winds in excess of 124 miles per hour. Ivan was the largest hurricane to strike the US in 2004, and one of the more powerful in recorded history.

9. The Winds of Earth

Which way is the wind blowing? The featured map can tell you this and much more, no matter your location on planet Earth.

10. The Cygnus Wall of Star Formation

Sometimes, stars form in walls -- bright walls of interstellar gas. In this vivid skyscape, stars are forming in the W-shaped ridge of emission known as the Cygnus Wall.

11. Penumbral Lunar Eclipse

Although shown in spectacular detail, the full face of Earth's most familiar satellite appears slightly darker than usual, in particular on the upper left, because it is undergoing a penumbral lunar eclipse.

12. Galaxies from the Altiplano

The central bulge of our Milky Way Galaxy rises over the northern Chilean Atacama altiplano in this postcard from planet Earth. Though at an altitude of 14,763 Feet, the strange beauty of the desolate landscape could almost belong to another world.

13. Herschel's Orion

This dramatic image peers within M42, the Orion Nebula, the closest large star-forming region. Using data at infrared wavelengths from the Herschel Space Observatory, the false-color composite explores the natal cosmic cloud a mere 1,500 light-years distant.

14. Gemini Observatory North

Shown sitting near the top of a mountain in Hawaii, the dome of the Gemini Observatory North houses one of two identical 26-foot diameter telescopes. Used with its Southern Hemisphere Twin Observatory in Chile, the two can access the entire sky from planet Earth.

15. Cylindrical Mountains On Venus

Such huge cylindrical mountains rising from the surface of Venus are known as coronas. Pictured here in the foreground is 500-kilometer wide Atete Corona found in a region of Venus known as the Galindo. The origin of massive coronas remains a topic of research although speculation holds they result from volcanism.

16. An Atlas V Rocket Launches OSIRIS-REx

Geçen ay OSIRIX-REx uzay aracını taşıyan büyük Atlas V roketi, Florida’da bulunan Fırlatma Bloğu 41’den havalandı. Bu robotik uzay aracı, Gök taşı Bennu’ya iniş yapmayı ve onun toprağından birazını Dünya’ya getirmeyi deneyecek.

17. The Antlia Cluster of Galaxies

The third closest cluster of galaxies to Earth after Virgo and Fornax, the Antlia cluster is known for its compactness and its high fraction of elliptical galaxies over spirals.

18. M45: The Pleiades Star Cluster

Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars even from the heart of a light-polluted city.

19. The Tulip in the Swan

About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms.

20. Cerro Tololo Trails

While early one moonlit evening car lights leave a wandering trail along the road to the Chilean Cerro Tololo Inter-American Observatory, setting stars also leave their trails in the sky.

21. Eagle Aurora over Norway

22. HI4PI: The Hydrogen Sky

Where are the Milky Way's gas clouds and where are they going? To help answer this question, a new highest-resolution map of the sky in the universe's most abundant gas -- hydrogen -- has been completed and recently released, along with its underlying data. Featured above, the all-sky map of hydrogen's 8-inch emission shows abundance with brightness and speed with color. Low radial speeds toward us artificially colored blue and low radial speeds away colored green.

23. Clouds Near Jupiter's South Pole from Juno

Recent images sent back by NASA's robotic Juno spacecraft are showing an interesting conglomeration of swirling clouds and what appear to be white ovals.

24. Propeller Shadows on Saturn's Rings

25. A Giant Squid in the Flying Bat

26. Haunting the Cepheus Flare

Spooky shapes seem to haunt this jeweled expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds faintly visible in dimly reflected starlight.

27. Moonset at Whitby Abbey

28. Halloween and the Ghost Head Nebula

Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the Northern Hemisphere). Perhaps a fitting tribute to this ancient holiday is this view of the Ghost Head Nebula taken with the Hubble Space Telescope.

29. Ghost Aurora over Canada
