Will NASA’s New Telescope Discover ET Life?
The spectacular first images from the James Webb Space Telescope are finally here and they do not disappoint.
After years of planning, construction, delays, and a cost of about $10 billion, we finally have the first images from the James Webb Space Telescope. Launched in December of 2021, the JWST is the largest and most powerful space telescope ever to be put in space.
Astronomers have waited a lifetime to see with such amazing clarity deep into space. JWST does this by operating in the infrared spectrum; it “sees” light that is outside the visible spectrum of our naked eye and previous telescopes like Hubble.
NASA released photos of the first five targets noting, “These first images from the world’s largest and most powerful space telescope demonstrate Webb at its full power, ready to begin its mission to unfold the infrared universe.”
We caught up with astronomer and Gaia News contributor Marc D’Antonio on the road in Arizona, to break down the images.
“I saw these images and the release of all five different images represent a different aspect of what this telescope can do — absolutely astonishing to me — from galaxies to gas clouds, this telescope hands down, has the ability to show us so much that we don’t understand.”
Most laypeople are impressed by the images, but what does an astronomer see? What should we be looking for?
“If you look at that large-scale shot, the deep field shot that the JWST took, that image encompasses a whole bunch of things happening there. In one case, you see galaxies that are stretched and curved. That is called gravitational lensing and we’re seeing the result of a galaxy cluster that’s in the foreground warping images of galaxies behind it. Those red galaxies on the outside, those galaxies are literally 13.6 billion years old. These are formed just after the Big Bang itself. This is kind of cool, I should say, it’s filling in the gaps. We haven’t been able to see back that far with any of our instrumentation. And when you say ‘see back that far,’ it really means the galaxies are so far away and moving so fast away from us, that their light has all shifted into the far-infrared where none of our telescopes have been able to penetrate until now.”
How will this help in the search for extraterrestrial life?
“This telescope is going to help us in the search for extraterrestrial life when it starts looking at exoplanet atmospheres. Now, it looked at the WASP-96 b planet’s atmosphere and it could see chemical traces in the atmosphere. This is something that’s extremely important because right now, up to this point, we have not been able to really, accurately look at atmospheres of planets around other stars. Now we have that capability. This is going to herald in an era of potentially finding another Earth-like planet with an oxygenated atmosphere.”
What does this latest discovery mean for the future of astronomy, space exploration, and even humanity?
“If you look at the JWST and the data they’re pulling in, and in a sense, all of these projects embody the human need to find answers. That’s what we’re doing, we’re hunting down answers to whether we’re alone in the universe and we’re trying to solve mysteries of the universe. The Webb’s first five images have already started to solve a huge number of mysteries.”
NASA's Curiosity Rover Found A Strange Metallic Object on Mars
NASA’s Curiosity rover recently stumbled upon an unusually shiny object in Mars’ Gale Crater. While the discovery received some coverage, it came at a time when most attention was focused on the space agency’s successful touchdown of the InSight Lander. NASA says it believes the object may be a meteorite and that it plans to study it more closely, though Curiosity was unable to pick it up on its first attempt.
The object, which NASA named Little Colonsay after an island in Scotland, has a distinct sheen to it, even noticeable through a black and white image the agency posted on its website.
“The planning team thinks it might be a meteorite because it is so shiny,” Susanne Schwenzer, a member of the Curiosity team, wrote. “But looks can deceive, and proof will only come from the chemistry.”
Curiosity has discovered meteorites in the past, though every irregular or eye-catching find sparks excitement, especially considering the recent discovery of a 12-mile wide body of water beneath the planet’s surface — a breakthrough confirming that Mars, at some point in its past, contained vast oceans and potentially harbored life. This possibility excites those who believe we may find evidence of a lost civilization or even fossils beneath the planet’s dusty surface.
The latest discovery apparently occurred the same day the InSight Lander touched down, as NASA’s JPL website said Curiosity was greeted by the Mr. Rogers’ jingle “Please would you be my neighbor,” before it got to work studying Little Colonsay.
This is not the first time Curiosity has come across anomalous looking objects, as it once found a piece of plastic, which was later alleged to have originated as debris from its landing.
Other strange looking objects the rover uncovered have convinced people that NASA found animals or artificial remnants it then covered up or ignored. However, the space agency insists these to be the product of pareidolia – a trick our minds play on us to make objects appear recognizable – though still, some remain skeptical.
Back in August, a very distinctly shaped object was discovered by Curiosity igniting speculation of an alien artifact or that it was a piece of the rover which was starting to fall apart. NASA tried to quell the excitement saying it tested the object and found it was a rock.
In other instances, online sleuths have claimed that the rover imaged animals including a squirrel and a duck on the Martian surface. These claims however, should probably be taken with a grain of salt, but if you’re interested you can find them here and here.
Even if most of Curiosity’s discoveries are just rocks, there are in fact, some truly unexplained anomalies discovered while observing the red planet – check them out in this episode of Deep Space :
