Astronomers at the University of Massachusetts Amherst and Arizona State University are developing the most sensitive millimeter-wavelength polarimetric camera on Earth, called TolTEC. The camera will use 7,000 detectors across three different bands in the electromagnetic spectrum. When it's completed, it'll be coupled with the 164-foot diameter Large Millimeter Telescope, the world's largest single-dish steerable millimetre-wavelength telescope, which is located in Puebla, Mexico.

In August, astronomers revealed that the nearest star system to the sun, Alpha Centauri, possesses a world roughly 1.3 times Earth's mass. Alpha Centauri consists of three stars — Alpha Centauri A, Alpha Centauri B, and a small red dwarf named Proxima Centauri — and this newfound planet appears to call Proxima Centauri home.

Mars has apparently claimed another robotic explorer. Europe's Schiaparelli Mars lander is most likely dead on arrival, after something went wrong during its parachute flight and its hover-rockets didn't ignite for long enough.

We know that there are multitudes of exoplanets scattered throughout the universe, but to date the only planets that we have been able to take a picture of are in our own cozy solar system. That might be about to change with a new initiative launched today that aims to send a telescope into low Earth orbit to take a picture of the binary Alpha Centauri system, which houses the two closest sun-like stars to our solar system

Kuaizhou, the smaller of Expace rockets, can carry a 200 kg payload to sun-synchronous orbit, making it ideal for launching clusters of microsatellites such as Cubesats.

Earth is very much powered by the sun. Beams of photons shoot down at us, dumping their energy into green plants. Then we eat the plants, or we eat the animals that eat the plants (or so on, up the food chain), and we too indirectly absorb that sweet solar energy.

It's still on Earth for the next two years, but the James Webb Space Telescope turned around to face the world this week, as it moved into position for preliminary optics testing. Once it's launched, JWST will study galaxy, star and planet formation in the universe using infrared wavelengths. For now, you can spy on the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Maryland where JWST is hanging out for the next few months, via the Webb Cam, here.
