Hubble Reveals Latest Portrait of Saturn
- investologia 7y agoLink to the original video: https://www.youtube.com/watch?v=8eJM0WlEjTs https://www.youtube.com/watch?v=8eJM0WlEjTs It might save you some time
- jankotek 7y agoOriginal image: https://hubblesite.org/image/4565/gallery https://hubblesite.org/image/4565/gallery It has smaller resolution compared to older Saturn images.
- ImaCake 7y agoI like your link better, it doesn't fail my filter of sensationalised title and provides interesting information in the description. Thankyou!
- mihaifm 7y agoThanks, much better. The posted article is insanely slow and clogged by ads (over 600 http requests)
- classified 7y agoPraised be the adblocker.
- mileycyrusXOXO 7y agoAdditionally, the posted article is a watered down version of this one; the journalist just rewrote paragraph by paragraph but in less detail.
- auslander 7y agoExposure is too long, all details lost.
- baal80spam 7y agoWow. It really looks like created in Blender or similar program!
- luoc 7y agoNa, blender renderings look more realistic these days ;)
- Areading314 7y agoHubble is a fantastic program that gets far too little credit IMO.
- Normal_gaussian 7y agoI'm not sure how much more credit it could get. It is extremely well known inside and outside of technical circles. Its images are often the face of astronomy as a whole - and credited as such.
- mobilefriendly 7y agoThere was a lot of criticism of the cost of the Hubble program in the beginning and then then mirrors failed after it was initally placed in orbit, turning Hubble into a national joke. NASA and Congress seriously considered abandoning Hubble then and a couple more times in the last two decades. https://spaceflightnow.com/2015/04/23/fixing-hubbles-blurry-vision/ https://spaceflightnow.com/2015/04/23/fixing-hubbles-blurry-...
- swebs 7y agoNice image, but the article is Buzzfeed-tier garbage.
- jcims 7y agoIn case it whet your appetite for more tastefully shot imagery of heavenly bodies: https://www.nasa.gov/mission_pages/cassini/images/index.html https://www.nasa.gov/mission_pages/cassini/images/index.html
- jsjohnst 7y agoI can’t get over how much the Mimas shots at that link remind me of the Death Star, but not surprisingly, I’m not the first to think that it seems.
- tabtab 7y agoThis backlit view from Cassini is one of the most amazing. It's not a view one can see from Earth. https://solarsystem.nasa.gov/resources/13315/in-saturns-shadow-color-exaggerated-view/ https://solarsystem.nasa.gov/resources/13315/in-saturns-shad... (Note: colors are enhanced a bit)
- jcims 7y agoTook me a minute to figure out the shadow at Saturn's equator, but it looks like the rings basically illuminate the entire planet and the shadow is just where the dust from the ring blocks the reflected light from the sun. Read an article about how Titan would possibly be a better location for humans to land first, and one of the benefits listed was that you could see Saturn's rings up close. Amen. :)
- tabtab 7y agoThe back rings are also in sharp shadow that happens to mostly match the shape of the planet from that angle. Re: Titan would possibly be a better location for humans to land first, and one of the benefits listed was that you could see Saturn's rings up close Titan's hazy atmosphere may make viewing Saturn itself tricky. It's debated how much it's "fogged out" and how often there are partial clearings in the haze. But at least the atmosphere can protect one from Saturn's radiation.

- ademarre 7y agoMike Massimino's book, Spaceman, includes a captivating account of what it was like to spacewalk on Hubble. He went on two Hubble servicing missions, including the final one when the WFC3 was installed—the camera that captured this new Saturn image.
- nsai 7y agoI read a journal claiming saturn would lose its rings over a period of time. Wonder how the solar system would look a few hundred thousand years later..
- gdubs 7y agoThis summer I gazed at Saturn through an inexpensive telescope my dad found at an antique store. The image was tiny, and rather black-and-white, but the rings were sharp and unmistakable. Despite the lack of resolution, it was one of the most magical things I’ve seen. Seeing Jupiter and its moons was pretty great too.
- jcims 7y agoSuch a cool feeling isn't it? Never forget the first time I saw those rings in person through a cheap telescope. It somehow places you in the same universe you've only read about till then.
- kashyapc 7y agoSome three years ago, I had the exact same experience—except that it was a high-end telescope at the observatory, with an equatorial mount and all other gear. I was mesmerized enough that I did a silly thing: pointed my Nexus 5's camera towards the telescope's eye piece to capture a hint of the Saturn. And ever since it's been my phone's wallpaper. That's[1] the result. It's an understatement to say "it's nowhere near as sharp", but you can clearly see the shape of the rings there. Another favourite of mine is the stunning blue-gold double star, Albireo[2]. Both the smaller blue star and the larger gold star are very distinct. Absolutely recommend it.

- hazeii 7y agoI was reminded of the same thing this summer, dragging an old telescope out to show Saturn to my son (for the first time). He was so excited to see a 'cartoon planet' for real, it gave my indifference to what you can see in a small telescope a sharp readjustment.
- tabtab 7y agoMy grandmother bought me a 60mm (main lens) telescope as a young teen. After a few nights of gazing, I learned how to spot things I hadn't seen at first, like the belts of Jupiter, and parts of the Orion nebula I hadn't before. The more practice the more you can see. I found it odd one had to "learn to see", but it's usually the case.
- exhilaration 7y agoWhy can't you see any stars in these pictures or the video they posted? I'd expect to see thousands of stars.
- hackerbabz 7y agoThe exposure is adjusted for Saturn which is much brighter than the stars.
- macintux 7y agoSame thing that people ask about the Moon landing photos. Where are the stars?
- exhilaration 7y agoThank you, that makes perfect sense. I would still love to see what it looks like with the naked eye.
- jonbronson 7y agoThat said, it would be amazing to see HDR images of these stellar bodies.
- ksaj 7y agoHere's a picture of some of the light even HDR wouldn't likely uncover: https://www.esa.int/spaceinimages/Images/2007/07/The_constellation_Orion_and_the_winter_Milky_Way https://www.esa.int/spaceinimages/Images/2007/07/The_constel... EDIT: A larger version of the image, with an equally huge url: https://m.esa.int/var/esa/storage/images/esa_multimedia/images/2007/07/the_constellation_orion_and_the_winter_milky_way/9242622-5-eng-GB/The_constellation_Orion_and_the_winter_Milky_Way_article_mob.jpg https://m.esa.int/var/esa/storage/images/esa_multimedia/imag...
- the8472 7y agoHDR and wide-spectrum are extensions along different measurement axes.
- neurostimulant 7y agoYou can even see the hexagonal pole from Hubble! Amazing! Full size image: https://www.spacetelescope.org/static/archives/images/original/heic1917a.tif https://www.spacetelescope.org/static/archives/images/origin...
- doe88 7y agoThe number of years of service and usefulness of Hubble is truly astonishing. I even remember news, almost joking about its initial mirror flaw which inflicted ironically an almost blindness, so much so people thought it would be fatal. NASA & Hubble seem to have had the last laugh on this one. Long live Hubble!
- tabtab 7y agoBut the repair costs were astronomical (pun semi-intended). However, the experience helped with future maintenance missions. Part of the reason for the flaw was paranoia about leaking tech to other countries that could result in spy scopes, which made testing tricky.
- SigmundA 7y agoWas trying to figure out why it looked photo-shopped to me. Realized the planet looks cut and pasted on to the rings due to the planets shadow on the rings being just barely visible behind giving it a black outline look. Well I'm assuming its the shadow...
- gpm 7y agoAlso the nearly precisely head on lighting, that comes from exactly 1 point. The lack of any atmospheric distortion. The perfectly clean background.
- metaphor 7y agoFrom the image titled The Moons of Saturn (annotated)[1], what relevance do the arrows denoting "North" and "East" have? I'm genuinely dumbfounded by the concept of cardinal directions in space. [1] https://www.spacetelescope.org/images/heic1917b/ https://www.spacetelescope.org/images/heic1917b/
- Cogito 7y agoThis is from memory, so apologies if vastly wrong. North is the direction out of the solar system plane in the same direction as Earth's North. East is prograde; tangent to the radial line from the sun, and in the direction of travel about the sun. Quickly googling I discovered that Saturn is considered to 'Rule the West' in some astrology circles, but alas I think that may not help this discussion.
