Cosmic Dawn Holds the Answers to Many of Astronomy’s Greatest Questions

Thanks to the most advanced telescopes, astronomers today can see what objects looked like 13 billion years ago, roughly 800 million years after the Big Bang. Unfortunately, they are still unable to pierce the veil of the cosmic Dark Ages, a period that lasted from 370,000 to 1 billion years after the Big Bang, where the Universe was shrowded with light-obscuring neutral hydrogen. Because of this, our telescopes cannot see when the first stars and galaxies formed – ca., 100 to 500 million years after the Big Bang.

This period is known as the Cosmic Dawn and represents the “final frontier” of cosmological surveys to astronomers. This November, NASA’s next-generation James Webb Space Telescope (JWST) will finally launch to space. Thanks to its sensitivity and advanced infrared optics, Webb will be the first observatory capable of witnessing the birth of galaxies. According to a new study from the Université de Genève, Switzerland, the ability to see the Cosmic Dawn will provide answers to today’s greatest cosmological mysteries.

Pencil December 18th (tentatively) into your calendar. That’s when James Webb probably launches

You may have heard this one before, but encouraging news comes from NASA, ESA, and Arianespace today: they are now targeting December 18, 2021 as the new launch date for the oft-delayed James Webb Space Telescope (JWST).

Finally, it’s starting to get real for the James Webb Space Telescope. Engineers are now preparing the long-awaited landmark telescope for transport to its launch site at Europe’s Spaceport in French Guiana.

In November (or early December) of this year, after many excruciating delays, NASA’s James Webb Space Telescope (JWST) will finally launch to space. As the most advanced and complex observatory ever deployed, the James Webb will use its advanced suite of instruments to observe stars, exoplanets, and galaxies in the near and mid-infrared spectrum. In the process, it will address some of the most enduring mysteries about the nature of the Universe.

When the time comes, the James Webb will fly aboard an Ariane 5 rocket from the European Space Agency (ESA) launch facility near the town of Korou, French Guayana. Overnight on August 17^th, 2021, the upper stage of that Ariane 5 began making its way in its cargo container from the ArianeGroup facility in Bremen, Germany, to Neustadt port, where it will board a ship bound for the ESA spaceport in French Guiana.

Want a LEGO James Webb Space Telescope? It Even Folds Up

As we all anticipate the launch of the James Webb Space Telescope (JWST) later this year (hopefully), LEGO designers are hoping for a “launch” of their own. A new LEGO design of JWST is currently gathering supporters on the LEGO Ideas website. If it gets enough support, LEGO will review it and possibly create it.

As of today (August 12, 2021), the idea has just under 1,500 supporters, with the goal of 10,000. If you want your very own JWST model, cast your vote of support!

What Would It Take To See Artificial Lights at Proxima Centauri B?

Is there an alien civilization next door? It’s…possible(ish). In late 2020, we discovered a signal from the direction of Proxima Centauri (not necessarily from Proxima Centauri), our closest neighbour star. Named BLC- 1 by project Break Through Listen, the signal is still being analyzed to ensure it isn’t simply an echo of our own civilization – typically what they turn out to be. But why not just directly look at planets in Proxima Centauri and see if a civilization is there?

From space, the most obvious sign somebody lives on Earth is the glow from the nightside of our planet. Our cities emit light that’s shed into the Cosmos. Problem is that our current generation of telescopes are not powerful enough to see lights on distant worlds. But several researchers are testing the capabilities of the next generation of telescopes already on the drawing board. The finding? Yes! if advanced enough…or glowy enough…we would be able to see if another civilization has the lights on at Proxima Centauri.

Another Delay for Webb, But This Time it’s Because of the Rocket, Not the Telescope

Officials from NASA and ESA this acknowledged the launch of the James Webb Space Telescope will very likely be delayed from the end of October to at least mid-November, 2021. As we reported last month, the usually reliable Ariane 5 has experienced problems on two previous launches where unexpected vehicle accelerations occurred when the fairing separated from the rocket. The fairing is the nose cone used to protect a spacecraft payload during launch and acceleration through Earth’s atmosphere.

“Indeed, there was an anomaly which has been mentioned recently in the media,” said Daniel de Chambure, acting head of Ariane 5 adaptations, during a media briefing on JWST. “The origin of the problem has been found; corrective actions have been taken.”

Concerns About James Webb’s Ariane 5 Rocket Might Push the Launch Back

A new report from the US Government Accountability Office (GAO) says that the launch of the long-awaited, highly anticipated James Webb Space Telescope (JWST) will very likely be delayed due to an anomaly identified in the Ariane 5 launch vehicle. Launch for JWST is currently scheduled for October 31, 2021, but that date could slip by at least a couple of weeks.

Webb Fully Unfurls for the Last Time on Earth. The Next Time Will Be in Space

The primary mirror of the long-awaited James Webb Space Telescope (JWST) was opened for the last time on Earth before the launch of the observatory, currently scheduled for October 31, 2021.

During some of the final checkouts before the telescope heads to space, engineers commanded the 18 hexagonal mirrors to fully expand and lock into place, just like they will do once the Webb telescope reaches its destination in space.

Jupiter Could Make an Ideal Dark Matter Detector

So, you want to find dark matter, but you don’t know where to look? A giant planet might be exactly the kind of particle detector you need! Luckily, our solar system just happens to have a couple of them available, and the biggest and closest is Jupiter. Researchers Rebecca Leane (Stanford) and Tim Linden (Stockholm) released a paper this week describing how the gas giant just might hold the key to finding the elusive dark matter.
