Construction Starts for Camera That Will Capture More Galaxies Than There Are People on Earth

Beginning in 2022, the most powerful digital camera ever built will start taking pictures of the southern sky. Over the course of a 10-year mission atop a mountain in Chile, the 3.2 gigapixel instrument is expected to accomplish a feat that might be hard to wrap your mind around. It will record tens of billions of galaxies floating in space–the first time a telescope will have ever identified more of the massive celestial objects than there are people on Earth.

Late last month, the U.S. Department of Energy gave its blessing for researchers to start building the camera that will sit at the heart of the Large Synoptic Survey Telescope (LSST). The gif above shows the three-ton, small-car-sized camera on the left. Illustrated is the system that slides filters down in front of the 3.2 gigapixel CCD, which senses light and is a digital camera’s version of film. The filters will let the camera record in light wavelengths from the near-ultraviolet to the near-infrared. Learn more and see images below.

The Twin Jet Nebula, or PN M2-9, is a striking example of a bipolar planetary nebula. Bipolar planetary nebulae are formed when the central object is not a single star, but a binary system, Studies have shown that the nebula’s size increases with time, and measurements of this rate of increase suggest that the stellar outburst that formed the lobes occurred just 1200 years ago.

T-51 days (October 14) - OA-4 Cygnus service module arrives at KSC Marking a major milestone in its prelaunch processing flow, the service module for the Cygnus spacecraft’s return to flight arrived at Kennedy Space Center earlier this week. The pressurized cargo module for the OA-4 mission arrived at Kennedy in early August, and technicians have been checking out the module ahead of cargo stowing. OA-4 marks a significant shift in the Cygnus program, not just because it is the spacecraft’s return to flight, but also the first flight of the Enhanced Cygnus. The cargo module is 3.9 feet longer than the initial Standard Cygnus, allowing the spacecraft to transport over 3,300 extra pounds of cargo. The Service Module also boasts new Orbital ATK-made Ultraflex solar arrays, which are lighter than the original rectangular arrays made by DutchSpace. The image below shows a comparison between the two versions of the spacecraft, with the Enhanced Cygnus on the right.

Final assembly and cargo stowage is expected to occur in late October and early November. Encapsulation inside an Atlas V 400-series payload fairing will occur in mid November, followed by rollout to SLC-41 and vehicle integration in late November. Currently, the launch of OA-4 is scheduled for December 3, though that date may move up or be pushed back depending on various factors. It will be the first flight of the spacecraft since an October 29, 2014 launch failure that destroyed the spacecraft and subsequently grounded the program. The enhanced Antares 200 rocket is undergoing final integration and assembly at Wallops Island, Virginia, and Orbital ATK teams are preparing for a period of pad testing. The next flight of Cygnus on an Antares is scheduled for some time in the first half of 2016. Until then, Orbital ATK purchased two Atlas V 401 rockets to launch their enhanced Cygnus spacecraft; these missions are designated OA-4 and OA-5. The second flight is slated for sometime in spring of 2016.

10 Intriguing Worlds Beyond Our Solar System

In celebration of the 20th anniversary of the first confirmed planet around a sun-like star (aka exoplanet), a collection of some interesting exoplanets has been put together. Some of these are rocky, some are gaseous and some are very, very cold. But there’s one thing each these strange new worlds have in common: All have advanced scientific understanding of our place in the cosmos. Check out these 10 exoplanets, along with artist’s concepts depicting what they might look like. For an extended list of 20 exoplanets, go HERE. 

1. Kepler-186f

Kepler-186f was the first rocky planet to be found within the habitable zone – the region around the host star where the temperature is right for liquid water. This planet is also very close in size to Earth. Even though we may not find out what’s going on at the surface of this planet anytime soon, it’s a strong reminder of why new technologies are being developed that will enable scientists to get a closer look at distance worlds.

2. HD 209458 b (nickname “Osiris”)

The first planet to be seen in transit (crossing its star) and the first planet to have it light directly detected. The HD 209458 b transit discovery showed that transit observations were feasible and opened up an entire new realm of exoplanet characterization.

3. Kepler-11 system

This was the first compact solar system discovered by Kepler, and it revealed that a system can be tightly packed, with at least five planets within the orbit of Mercury, and still be stable. It touched off a whole new look into planet formation ideas and suggested that multiple small planet systems, like ours, may be common.

4. Kepler-16b

A real-life “Tatooine,” this planet was Kepler’s first discovery of a planet that orbits two stars – what is known as a circumbinary planet.

5. 51 Pegasi b

This giant planet, which is about half the mass of Jupiter and orbits its star every four days, was the first confirmed exoplanet around a sun-like star, a discovery that launched a whole new field of exploration.

6. CoRoT 7b

The first super-Earth identified as a rocky exoplanet, this planet proved that worlds like the Earth were indeed possible and that the search for potentially habitable worlds (rocky planets in the habitable zone) might be fruitful.

7. Kepler-22b

A planet in the habitable zone and a possible water-world planet unlike any seen in our solar system.

8. Kepler-10b

Kepler’s first rocky planet discovery is a scorched, Earth-size world that scientists believe may have a lava ocean on its surface.

9. Kepler-444 system

The oldest known planetary system has five terrestrial-sized planets, all in orbital resonance. This weird group showed that solar systems have formed and lived in our galaxy for nearly its entire existence.

10. 55 Cancri e

Sauna anyone? 55 Cancri e is a toasty world that rushes around its star every 18 hours. It orbits so closely – about 25 times closer than Mercury is to our sun – that it is tidally locked with one face forever blistering under the heat of its sun. The planet is proposed to have a rocky core surrounded by a layer of water in a “supercritical” state, where it is both liquid and gas, and then the whole planet is thought to be topped by a blanket of steam.
