Amazing Animated GIFs Capture Nebulae in 3D Using Artificial Parallax

starparallax

Parallax 3D images use two photos captured from slightly different vantage point to create the appearance of depth. In astrophotography, however, the distance between human cameras and distance objects are so great that real parallax generally cannot be achieved.

Finnish astrophotographer J-P Metsavainio has developed a brilliant experimental technique that overcomes this (kinda): he converts astrophotographs into 3D volumetric models, and then uses those models to create dazzling 3D animations of nebulae.

The Moon and Venus Captured in a Single Photograph

Behold, a photograph of the moon. Can you see it? No, it’s not that tiny bright crescent you see… The moon is that faint giant crescent. That tiny one to its left is Venus. Hungarian astrophotographer Iván Éder captured this beautiful photograph back in 2004 from Budapest, Hungary.

This Mind-blowing Photo of the Milky Way Shows 84 Million Stars in 9 Billion Pixels

Astronomers at the European Southern Observatory’s Paranal Observatory in Chile have released a breathtaking new photograph showing the central area of our Milky Way galaxy. The photograph shows a whopping 84 million stars in an image measuring 108500×81500, which contains nearly 9 billion pixels.

This is the Most Zoomed-In Photograph Ever Created by Mankind

What you’re looking at is the most zoomed-in photo ever shot by mankind. Titled the eXtreme Deep Field (XDF), it’s a followup to the famous Hubble Ultra-Deep Field photo created in the mid-2000s. Scientists combined 10-years-worth of Hubble Space Telescope photos to create this resulting image that shows 5,500 individual galaxies, some of which are one ten-billionth the brightness of what our human eyes can see.

The World’s Most Powerful Digital Camera Snaps Its First Photos

On a mountaintop in Chile is the most powerful digital camera mankind has ever constructed. Called the Dark Energy Camera, the phone booth-sized device shoots 570-megapixel photographs using an array of 62 separate CCD sensors and a 13-foot light-gathering mirror. Planning and building the thing took 120 scientists from 23 international organizations a whopping 8 years.

This past week, the researchers behind the project announced the first fruits of their labor: massive photographs that show patches of the sky 20 times the size of the moon (as seen from Earth).

The Curiosity Rover’s Descent into Mars as an Amazing HD Video

When NASA’s Curiosity rover performed its “seven minutes of terror” landing on Mars a couple weeks ago, the Mars Descent Imager (MARDI) camera had the task of capturing 1600×1200 (~1.9 megapixel) photographs at a rate of 5 frames per second. The camera began snapping away from when the heatshield separated to a few seconds after the rover touched down. The amazing high-definition video above was created with these photographs, showing what it’s like to fall onto the surface of the red planet.

What Night Sky Photos Would Look Like if Other Planets Replaced the Moon

What would photographs of the night sky look like if other planets in our solar system replaced the Moon? This beautiful video by 3kingAmazing (remixed using a video by Brad Goodspeed) shows the answer.

If you liked this video, check out what landscape photos would look like if Earth had Saturn’s rings and what night sky photos will look like over the next 7 billion years.

A High Definition Time-Lapse of Venus Flying Past the Sun

There was a much-hyped transit of Venus yesterday in which Venus appeared as a small black circle moving across the face of the sun. This rare phenomenon occurs in pairs of eight years separated by more than a century: the previous transit was in 2004, but the next one won’t occur until 2117. If you missed out, don’t worry — there’s a boatload of beautiful photos and videos out there that can give you an even better view than what your eyes would have seen. The amazing high-definition video above was created using images from NASA’s Solar Dynamics Observatory.

Canon 60Da: An Astrophotography DSLR

Canon has announced the new 60Da, a DSLR geared towards astrophotographers and the successor to the 20Da. So what’s different about this camera? A “modified infrared filter and a low-noise sensor with heightened hydrogen-alpha sensitivity” which allows it to capture photos of “‘red hydrogen emission’ nebulae and other cosmic phenomena”:

The improved infrared-blocking filter is a modification suited specifically toward astronomy enthusiasts to achieve a hydrogen-alpha light sensitivity that is approximately three times higher than that of a normal Canon DSLR camera. This produces a 20-percent higher transmittance of Hydrogen Alpha line, or H α wavelength, allowing astronomers to capture crisp, clear images of reddish, diffuse nebulae.

The basic specs remain unchanged from the original 60D: an 18MP APS-C sensor, 9-point AF, and a 3-inch articulated screen. Also included with the camera is a remote controller adapter and an AC adapter kit. Stargazers will be able to snag one later this month for $1,499.

A Beautiful Composite Photo Showing the Moon, Jupiter, and Venus

This past Sunday, Jupiter and Venus put on a show by lining up with our moon (a conjunction). Rick Ellis of Toronto, Canada managed to create the awesome photo of the event seen above by capturing 31 separate frames. Each photo was taken 5 minute apart and had an exposure time of 5 seconds.
