>IC1396 is a huge cloud of gas and dust, a star-forming factory 100 light years across. Massive, hot, young stars in the center have blown an enormous cavity in the center of the nebula, their fierce stellar winds and blasting ultraviolet light eating the

I just finished rewatching Contact. In time, maybe. But even our ancestors won’t be life as we imagine it. It may not matter…life is likely everywhere anyway. 4 billion years from now a whole new planet with intelligent life could emerge just like on
We’re located in one of the many arms of the Milky Way, seeing as it’s a spiral galaxy. What you’re seeing here is a view of the galactic center, as you get closer and closer to the center the stars and gas become more
Yes, that big port city in the lower center is Tunis. And Cagliari is easily visible on the southern coast of Sardinia (the island on the left side).
Real explanation is crazier — plumes of material being ejected from around a young star at hundreds of kilometers per second. H-H objects last only a few thousand years which is very short on astronomical timescales.
Description: > This view of the twilight sky and Martian horizon taken by NASA’s Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image, and our moon is just
I audibly gasped when I saw that picture. I’m currently at the eleventh crow wing lake, in Minnesota. So little light pollution. My cousin and I went out and stared at the stars for an hour and a half before looking at the clock.
I think he was on about how detailed and “normal” it is, you can see the tiny threads sticking up on the badge on his right arm and the fact he is using (what I presume to be) a fairly normal looking oxygen measure
By composite he means merging two (or more) photographs, which is generally different than “faking.” The fake part in this photograph is that our eyes would not be able to pick up as much detail of the milky way as the camera has. Our
I actually tried to take a photo in this way, but it don’t convey the idea at all, the sphere covers the moon…and it is not clear that the moon is behind! 🙂
Almost four light-years, according to [the source](http://astronomynow.com/2015/08/05/the-ghost-of-a-dying-star/). The distance between Sun and Earth is eight light-minutes. This might give you a rough estimation about its size. It doesn’t hurt to provide some more info, OP 😉 At least a link to the source. Anyway,
When I do it, I plant my feet as firmly on the ground as I can, I also toss my jacket over my head/the eye piece so that I can sort of adjust my eyes better/block out other light. Then I slowly move the
The short, pithy answer is the age of the universe and stars. In detail – our sun is burning H2->He via the [Proton-Proton chain reaction](https://en.wikipedia.org/wiki/Proton%E2%80%93proton_chain_reaction) in the outer layers. In the denser and hotter core, it’s probably generating He via the [C-N-O](https://en.wikipedia.org/wiki/CNO_cycle). C/N/O is
Don’t want to argue over something as silly as this, but there is actually no vantage point from which actual Io could appear that size in relation to actual Jupiter. Io is one of the closest moons to Jupiter and as absolutely dwarfed by
Explanation: Why would a small part of the Sun appear slightly dark? Visible above is a close-up picture of a sunspot, a depression on the Sun’s face that is slightly cooler and less luminous than the rest of the Sun. The Sun’s complex magnetic
It’s frustrating, but humbling at the same time. I had driven through the Tetons before with my Father when I was 11. 14 years later with a friend I was looking forward to spending more time there, but the haze was insanely thick. It
This is what I was going to say. It’s a great photo! I spend a lot of time looking at space photos for inspiration to paint, and this is one of those too-good-to-paint types of photos. As a painting, it would look super fake.
This is sick! It gave me a “living in the future” feeling. I mean, I wouldn’t have felt like this if it was a mere space photo from close to Saturn, but this is art. I have trouble grasping that we/humanity went there and
[Taken from NASA’s Astronomy Photo of the Day for July 3rd](http://apod.nasa.gov/apod/ap130703.html) > It may appear, at first, like the Galaxy is producing the lightning, but really it’s the Earth. In the foreground of the above picturesque nighttime landscape is the Greek Island of Corfu,
I’ll spare the dramatic details of the night but it involved a long drive to the middle of nowhere. There were a lot of bugs. Worth it for the shots I came home with. In case anyone’s interested, settings are: 16mm | F2.8 |
This is one composite image from tonight’s total lunar eclipse. One image was used to properly expose the moon and one image was used to properly expose the stars. The moon has been kept the same size. I’m an amateur photographer who likes to
If Bigelow Aerospace’s inflatable modules work out, constructing a space station the size of the ISS will no longer require nearly as much lift power. It might not even require an external robotic arm to place the modules. Right now the first expandable module
More complicated than that. Voyager vidicons had multiple filters that were targeted on specific wavelengths of lights. These wavelengths were selected for many reasons including the expected compositions of the outer planet atmospheres. For example, methane is more transparent to certain wavelengths than others
I believe the opening sequence to the new Cosmos tv show is entirely computer generated imagery (CGI). I grabbed some [frames from the intro](http://imgur.com/a/oG9es) for comparison and, while it is similar to both the Ring nebula and the [Helix nebula](http://www.space.com/18484-vistas-look-at-the-helix-nebula.html), I believe it is
