No need for digital vintage filters on these awesome shots.
On October 24, 1946, the world was introduced to the first photograph from space, a shot of our tiny planet taken 65 miles above Earth. The artist behind this iconic image was a V-2 rocket, programmed to capture a frame every 1.5 seconds before deliv...

A Night at Poker Flat

Four NASA suborbital sounding rockets leapt into the night on January 26, from the University of Alaska's Poker Flat Research Range. This time lapse composite image follows all four launches of the small, multi-stage rockets to explore winter's mesmerizing, aurora-filled skies. During the exposures, stars trailed around the North Celestial Pole, high above the horizon at the site 30 miles north of Fairbanks, Alaska. Lidar, beams of pulsed green lasers, also left traces through the scene. Operating successfully, the payloads lofted were two Mesosphere-Lower Thermosphere Turbulence Experiments (M-TeX) and two Mesospheric Inversion-layer Stratified Turbulence (MIST) experiments, creating vapor trails at high altitudes to be tracked by ground-based observations.

Video of the biggest photograph ever taken

This is stunning! Light years between every bright dot. Takes some getting your head around.

Well said +Scott Hanselman and shame on you +Download.com et al.

This sort of Dark UI Pattern needs to stop. Be wary and avoid sites that practice this.

Jets from Comet Churyumov-Gerasimenko

Where do comet tails come from? Although it is common knowledge that comet tails and comas originate from comet nuclei, exactly how that happens is an active topic of research. One of the best images yet of emerging jets is shown in the featured image, taken last November by the robotic Rosetta spacecraft in orbit around the Comet 67P/Churyumov-Gerasimenko (Comet CG), and released last month. The overexposed picture shows plumes of gas and dust escaping numerous places from the Comet CG's nucleus as it nears the Sun and heats up. Although Comet CG is currently further out from the Sun than Mars, its orbit will take it almost as close as the Earth this coming August, at which time its jet activity is expected to increase by a factor of about 100. You've likely seen some debris from comet nuclei before but in another form -- when sand-sized bits end their journey through the Solar System by impacting the atmosphere of Earth as meteors.

Yep, that's a pretty impressive photo.
 
'Heavenly' Ice Halos Form Over New Mexico

It's not quite like finding diamonds in the sky, but a photographer in Red River, New Mexico, was lucky enough to catch rainbow-like arcs and pillars of light blazing over a snowy landscape last week. This example of sunlight run amok is caused by the collision of light and ice crystals high in Earth's atmosphere.
http://news.nationalgeographic.com/news/2015/01/150114-ice-halo-weird-weather-phenomena-science/

A halo (from Greek ἅλως, halōs;[1] also known as a nimbus, icebow or gloriole) is an optical phenomenon produced by light interacting with ice crystals suspended in the atmosphere, resulting in a wide variety of colored or white rings, arcs and spots in the sky. Many halos are near the Sun or Moon, but others occur elsewhere or even in the opposite part of the sky. Among the most well known halo types are the circular halo (properly called the 22° halo), light pillars and sun dogs, but there are many more; some of them fairly common, others (extremely) rare.
The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds high (5–10 km, or 3–6 miles) in the upper troposphere, but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals is responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting light between their faces, sending shafts of light in particular directions.
Atmospheric phenomena such as halos were used as part of weather lore as an empirical means of weather forecasting before meteorology was developed. They often do mean that rain is going to fall within the next 24 hours as the cirrostratus clouds that cause them can signify an approaching frontal system.

Best photosphere ever? I'd probably agree with that. This is a must see.

Scientists achieve levitation via sound waves

A group of researchers at the University of Tokyo make stuff levitate. The idea itself is not entirely novel. What’s new here, though, is the ability to move those materials in three dimensions.
