Twinkling stars might make for spectacular viewing on a hot summer’s night, but they are an absolute nightmare to astronomers. That twinkling is caused by disturbances in the Earth’s atmosphere, and can wreak havoc on brightness readings, a key tool for astronomers everywhere. Those readings are used for everything from understanding galaxy formation to the detection of exoplanets.
Astronomers now have a new potential location to try to avoid the twinkling. Only one problem though: it’s really cold, especially this time of year. A team of astronomers from Canada, China, and Australia have identified a part of Antarctica as the ideal place to put observational telescopes. Now the challenge becomes how to actually build one there.

The oldest stars in the Universe are cloaked in darkness. Their redshift is so high, we can only wonder about them. The James Webb Space Telescope will be our most effective telescope for observing the very early Universe, and should observe out to z = 15. But even it has limitations.
To observe the Universe’s very first stars, we need a bigger telescope. The Ultimately Large Telescope.

Japan has suspended its funding contribution to the controversial Thirty Meter Telescope (TMT) in Hawaii. An international consortium is behind the TMT, which was proposed for the summit of Mauna Kea. Mauna Kea is one of the most desirable observing locations on Earth. It’s already host to several observatories, including the Subaru Telescope and the Keck Observatory. The $1.4 billion TMT would be the most powerful telescope there.

Put “James Webb Telescope launch” into your search engine and you’ll be flooded with links, some reaching back to the ‘scope’s first proposed launch date in 2010. The delayed launch of the space telescope is a running theme in the space community, even though we all know it’s going to be worth the wait. So nobody will be surprised by this latest development in the story of the world’s most anticipated telescope.

Meade Instruments, a company familiar to any backyard astronomer who’s drooled over their telescopes, has filed for bankruptcy. The company has fallen on hard times in recent years, as they’ve faced increasing competition. Meade also recently lost a lawsuit, which pushed them over the edge into bankruptcy.
The company is based in Irvine, California, and was founded in 1972. They started out selling small refracting telescopes. They expanded into Newtonian reflectors and Schmidt-Cassegrain telescopes over the years. Now, they sell telescope models worth upwards of $10,000.

The U.S. House of Representatives have passed a bill to change the name of the Large Synoptic Survey Telescope (LSST.) Instead of that explanatory yet cumbersome name, it will be named after American astronomer Vera Rubin. Rubin is well-known for her pioneering work in discovering dark matter.

South America, especially the Atacama Desert in Chile has become one of the best places in the world to put a telescope. It’s dry, high, and the nights are clear. Today we’ll talk about the monster telescopes already in operation in this region, and the big ones coming soon.

WFIRST ain’t your grandma’s space telescope. Despite having the same size mirror as the surprisingly reliable Hubble Space Telescope, clocking in at 2.4 meters across, this puppy will pack a punch with a gigantic 300 megapixel camera, enabling it to snap a single image with an area a hundred times greater than the Hubble.
With that fantastic camera and the addition of one of the most sensitive coronagraphs ever made – letting it block out distant starlight on a star-by-star basis – this next-generation telescope will uncover some of the deepest mysteries of the cosmos.
Oh, and also find about a million exoplanets.

Finding planets is old news, we now know of thousands and thousands of the places. But the terrible irony is that we can only see a fraction of the planets out there using the traditional methods of radial velocity and transits. But the new telescopes will take things to the next level and image planets directly.

Our newest planet-hunting telescope is up and running at the ESO’s Paranal Observatory in the Atacama Desert in Chile. SPECULOOS, which stands for Planets EClipsing ULtra-cOOl Stars, is actually four 1-meter telescopes working together. The first images from the ‘scopes are in, and though it hasn’t found any other Earths yet, the images are still impressive.
