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.

Solar System: Top 5 Things to Know This Week

1. A Ceres of Fortunate Events

Our Dawn mission continues its exploration at Ceres, and the team is working with the data coming back to Earth, looking for explanations for the tiny world’s strange features. Follow Dawn’s expedition HERE.

2. Icy Moon Rendezvous

One of the most interesting places in the entire solar system is Saturn’s moon Enceladus, with its underground ocean and spectacular geyser plume. This month, the Cassini spacecraft will be buzzing close by Enceladus several times, the last such encounters of the mission. On October 14, Cassini will perform a targeted flyby at a distance of just 1,142 miles (1,838 kilometers) over the moon’s northern latitudes. Ride along with Cassini HERE.

3. Make Your Own Mars Walkabout

You can retrace Opportunity’s journey, see where the Curiosity rover is now, or even follow along with fictional astronaut Mark Watney from The Martian movie using the free online app MarsTrek. The app lets you zoom in on almost any part of the planet and see images obtained by our spacecraft, so you can plan your on Red Planet excursion. Take a hike HERE.

4. Elusive Features on Jupiter

New imagery from our Hubble Space Telescope is capturing details never before seen on Jupiter. High-resolution maps and spinning globes, rendered in the 4K Ultra HD format, reveal an elusive wave and changes to Jupiter’s Great Red Spot. Explore Jupiter HERE.

5. Mr. Blue Sky

Another week, another amazing picture from Pluto. The first color images of Pluto’s atmospheric hazes, returned by our New Horizons spacecraft last week, reveal that the hazes are blue. Who would have expected a blue sky in the Kuiper Belt? Most of the data collected during July’s Pluto flyby remains aboard the spacecraft, but the team publishes new batches of pictures and other findings on a weekly basis. Keep up with the latest HERE.

Solar System: Top 5 Things to Know This Week

It’s only Tuesday and this week is already filled with news about our solar system. Here are the top five things to know this week:

1) Mars!

With five spacecraft in orbit and two rovers exploring the ground, there’s always something new and interesting about the Red Planet. Yesterday things got even more exciting when we released the most compelling evidence yet that liquid water sometimes flows on Mars today.

2) HTV-5 Cargo Ship

On Monday, the HTV-5 cargo ship was released from the International Space Station to burn up as it reenters Earth’s atmosphere. The HTV-5 carried a variety of experiments and supplies to the space station, and was docked for five weeks.

3) Pluto Continues to Excite

If you haven’t been keeping up with the weekly releases of newly downloaded pictures from our New Horizons spacecraft, you are definitely missing out. But don’t worry, we have you covered. The latest updates can be found HERE, be sure to follow along as new information is released. More images are scheduled to be featured on Oct. 1.

4) Cassini Mission

This week on Sept. 30, our Cassini spacecraft will reach the closest point to Saturn in it’s latest orbit around the planet. Just to put things in perspective, that will be Cassini’s 222nd orbit around Saturn! Learn more about this mission HERE.

5) What Happened to Mars’ Atmosphere?

Believe it or not, the Martian atmosphere we see today used to be much more substantial many years ago. What happened? Our Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has been in orbit around Mars for one Earth year, searching for the answers. Learn more HERE.

• Use the hand you write with.

• Make a fist with your thumb outside, not tucked inside. If it’s tucked inside your fist, when you punch someone, you might break your thumb. The thumb goes across your fingers, not on the side.

• Don’t be like in the movies—don’t aim for the face. Face punches don’t usually stop people, and you can miss when they duck their head or break your hand on their jaw. If you want to get away quickly, or end a fight, aim for the chest, or the ribs. If you really want to do some damage, e.g., you’re being attacked, aim for the throat, which will make it hard for your attacker to breathe for a hot minute.

• When you punch, you want to aim and hit with your first two knuckles. Not the flats of your fingers, and not your ring or pinky knuckles, which can break more easily. You can use your weight, if you’re on your feet, to add wallop, and spring into a punch with your feet and torso.
