Webb Telescope Builders “Are Questioning Previous Science”

In an interview at Futurism, Webb astronomer Garth Illingworth shares how the new findings are shaking up what we think we know about the universe

Futurism’s Maggie Harrison recently interviewed UC Santa Cruz astronomer Garth Illingworth, one of the developers of the James Webb Space Telescope. His observations put the astronomers’ astonishment at the unexpected new findings of very old, developed galaxies in perspective: And I would just say, you know, when I was sitting there watching the first images, I was just blown away by their beauty and the character there, the information. But one of the things I was thinking afterwards was: in that hour, I saw, like, six sets of data. I have to say, that’s more data than I’ve ever seen from anything in any sort of reasonable time period in my whole life. Scientists are going to be working on…

The Webb gets a good closer look at an exoplanet

Exoplanets are hard to spot but the James Webb Space Telescope got an image of one (HIP 65426b), reported September 1: The planet is more than 10,000 times fainter than its host star and about 100 times farther from it than Earth is from the Sun (~93 million miles), so it easily could be spotted when the telescope’s coronagraphs removed the starlight. The exoplanet is between six and 12 times the mass of Jupiter—a range that could be narrowed once the data in these images is analyzed. The planet is only 15 million to 20 million years old, making it very young compared to our 4.5-billion-year-old Earth.

Astrophysicist: Webb Finds May Bring “Revolutionary Changes”

It doesn’t disprove the Big Bang, says Brian Koberlein… but read the fine print. And Fermilab’s Don Lincoln gets the religious implications all wrong

Recently, the James Webb Space Telescope started sending back observations about our universe that started quite the tizzy. Did the Big Bang even happen? More focused: If it happened, did it happen when and how the conventional story runs? At Universe Today, astrophysicist Brian Koberlein tries to put the matter in perspective: Most significantly, it has found more galaxies and more distant galaxies than there should be, and that could lead to some revolutionary changes in our standard model. Our current understanding is that after the big bang the universe went through a period known as the dark ages. During this period the first light of the cosmos had faded, and the first stars and galaxies hadn’t yet formed. Webb…

Theoretical Physicist: Can’t Avoid a Beginning for Our Universe

Recent shakeups from the James Webb Space Telescope images invite fundamental questions like, Does the universe have a beginning?

The recent flutter over whether the James Webb Space Telescope’s data stream is a plus or a minus for the Big Bang and the Standard Model of the universe touched on some interesting cosmological issues. The Big Bang and the Standard Model support the assumption that our universe is finite and had a beginning. Could it have been eternal — with an infinite past instead of a beginning? The trouble is, as we saw last Saturday, when we try to apply concepts like infinity — typically used in mathematics — to the physical world, the basis of reality can collapse into absurdity. The world science observes seems to be finite; time starts at a certain point, flows in one direction,…

James Webb Space Telescope Shows Big Bang Didn’t Happen? Wait…

The unexpected new data coming back from the telescope are inspiring panic among astronomers

Physicist Eric J. Lerner comes to the point: To everyone who sees them, the new James Webb Space Telescope (JWST) images of the cosmos are beautifully awe-inspiring. But to most professional astronomers and cosmologists, they are also extremely surprising—not at all what was predicted by theory. In the flood of technical astronomical papers published online since July 12, the authors report again and again that the images show surprisingly many galaxies, galaxies that are surprisingly smooth, surprisingly small and surprisingly old. Lots of surprises, and not necessarily pleasant ones. One paper’s title begins with the candid exclamation: “Panic!” Why do the JWST’s images inspire panic among cosmologists? And what theory’s predictions are they contradicting? The papers don’t actually say. The…

Exoplanets: As the Data Streams Back… the Picture Comes In

China is now focusing on the search for a planet like Earth, using the Earth 2.0 Telescope (ET). Astronomer Jian Ge believes his team can find 17

In recent exoplanet news: ● China is now focusing on a search for a planet like Earth: Most likely, such a planet does exist, but in the relatively nascent field of exoplanet research, no one has yet been able to find it. That is not for lack of trying. Kepler spent nine years searching over 150,000 stars, and while it detected almost 3,000 new exoplanets, none met the criteria of being Earth-sized in the habitable zone of a sun-like star. Bad luck might have played a role – the new paper’s authors even calculated that statistically, Kepler probably should have found at least one Earth-sized planet in a habitable zone.

Some Cold Giant Planets May Be Habitable, Researchers Say

Life could exist outside the expected habitable zone if a massive planet can hang onto insulating gases in its atmosphere

Rocky exoplanets with an atmosphere of hydrogen and helium gases could have liquid water on the surface, like Jupiter’s moon Europa, and could thus host life. The question is whether the surface water sticks around long on “cold super-Earths,” that are ten times the mass of our planet: Now, new calculations described in a paper published Monday in the journal Nature Astronomy suggest that the surface conditions of these worlds could have been temperate for more than enough time for life—for 5 billion to 8 billion years. Earth is only about 4.5 billion years old, by comparison, and life emerged here about 3.7 billion years ago.
