If everything goes as planned, James Webb Space Telescope will go in space and become operational in the end of 2018. It’s sometimes regarded as a successor to Hubble Space Telescope. If you could decide, where would you point it’s “eye” for a first look?

I’d point it at a protoplanetary disk to see what exoplanets look like in formation! I was blown away when astronomers using ALMA (Atacama Large Millimeter/Submillimeter Array) got this image of one (https://public.nrao.edu/news/pressreleases/planet-formation-alma), so I can’t wait to see what JWST reveals in the infrared for systems like this.

I’m looking forward to seeing how far in space and time the Webb can look. Will it see the very first star formation in the Universe? Will it provide a glimpse at what the earliest galaxies looked like? Will we be able to observe the formation of the first planetary systems? Will we see back even farther to moments after the Big Bang? Will JWST give us more information about the Cosmic Dark Ages? It is expected to be able to see objects between 10 to 100 times fainter than Hubble can see, so I’m hoping its ‘first light’ will test the limits of how far JWST can see.

James Webb is perfect for looking at planetary formation and early galaxies from the birth of the Universe. It’s the kind of science where it’s hard to predict exactly what we’ll find, but that’s the point! Whatever it is, it’s sure to be fascinating and improve our understanding of the cosmos and our place in it. I hope it helps shed more light (infrared of course!) on planet formation and how typical our solar system is likely to be.

Why not use the James Webb Telescope to search for alien planets? It is alleged by conspiracy claptrap that the Grays, an alleged species of extraterrestrials, are from Zeta Reticuli, which is a wide binary star system in the southern constellation of Reticulum. From the southern hemisphere the pair can be observed as a naked eye double star in very dark skies. Based upon parallax measurements, Zeta Reticuli is located at a distance of about 39 light-years from the Earth. Both stars are solar analogs and share comparable characteristics with the Sun. Although the kinematics of these stars imply that they belong to a population of older stars, the properties of their stellar chromospheres indicate they are only about 2 billion years old. On September 20, 1996, astronomers reported a provisional discovery of a hot Jupiter around Zeta-2, but the discovery was briefly retracted as the signal was caused by pulsations of the star. In 2002, moreover, Zeta-1 was scanned at an infrared wavelength of 25 μm, but no extrasolar planets were found. The James Webb could possibly detect extrasolar planets, if any, around Zeta Reticuli and perhaps close the books on the Grays for good.

James Webb should be able to look right back the edge of the observable Universe and see some of the earliest structures forming. It’ll be amazing to finally get a picture of what the Universe looked like so long ago, when everything was much closer together. How did those early galaxies form so quickly? When did the first supermassive black holes form? I can’t wait to find out the answers.
