The Orion Nebula
This Is the Most Detailed Image of the Universe Ever Captured
NASA has just published the most detailed view of the Universe ever taken. It’s called the Extreme Deep Field—or XDF for short. It took ten years of Hubble Space Telescope photographs to make it and it shows some the oldest galaxies ever observed by humans, going 13.2 billion years back in time.
It’s a mindblowing, extremely humbling view. Not only for what it shows, but for what it doesn’t show. While this image contains about 5,500 galaxies, it only displays a tiny part of the sky, a ridiculously small slice of the Universe.

Astronomy Photo of the Day: 04/21/14 - Saturn Lit Up By the Sun
If you aren’t already familiar with this image, your life is incomplete without you even knowing it. This is the first and most spectacular of the images of Saturn taken by the Cassini spacecraft.
Unlike most of Cassini’s images, this one is completely different, for in this image, Saturn is eclipsing the sun. At the center of the image is the body of the gas giant, which in itself is partially lit by the reflection of light from its ring system. Of course, as you move away from center, the majestic rings shine with incredible brightness. Because of this, the image actually revealed the presence of a series of rings that were unknown to scientists at the time.
And, if this image wasn’t already cool enough, it’s about to get cooler. Of course, you see the thick bright bands of Saturn’s iconic rings, and you see the slightly more separated, fainter ring system (i.e. the second farthest ring from the planet, or the G ring). In left hand side, near the 10 o’clock position, you’ll see a little dot. That is the Earth. “That’s here. That’s home. That’s us.”

This Is Big: Scientists Just Found Earth’s First-Cousin
Right now, 500 light years away from Earth, there’s a planet that looks a lot like our own. It is bathed in dim orangeish light, which at high noon is only as bright as the golden hour before sunset back home.
NASA scientists are calling the planet Kepler-186f, and it’s unlike anything they’ve found. The big news: Kepler-186f is the closest relative to the Earth that researchers have discovered.
It’s the first Earth-sized planet in the habitable zone of another star—the sweet spot between too-hot Mercury-like planets and too-cold Neptunes— and it is likely to give scientists their first real opportunity to seek life elsewhere in the universe. “It’s no longer in the realm of science fiction,” said Elisa Quintana, a researcher at the SETI Institute.
But if there is indeed life on Kepler-186f, it may not look like what we have here. Given the redder wavelengths of light on the planet, vegetation there would sprout in hues of yellow and orange instead of green.
