The Webb Telescope Is Just Getting Started

 

The first scientific results are coming in, and the $10 billion instrument is working even better than astronomers had dared to hope.

For three days in December, some 200 astronomers filled an auditorium at the institute to hear and discuss the first results from the telescope. An additional 300 or so watched online, according to the organizers. The event served as a belated celebration of the Webb’s successful launch and inauguration and a preview of its bright future.

One by one, astronomers marched to the podium and, speaking rapidly to obey the 12-minute limit, blitzed through a cosmos of discoveries. Galaxies that, even in their relative youth, had already spawned supermassive black holes. Atmospheric studies of some of the seven rocky exoplanets orbiting Trappist 1, a red dwarf star that might harbor habitable planets. (Data suggest that at least two of the exoplanets lack the bulky primordial hydrogen atmospheres that would choke off life as we know it, but they may have skimpy atmospheres of denser molecules like water or carbon dioxide.)

“We’re in business,” declared Bjorn Benneke of the University of Montreal, as he presented data of one of the exoplanets.

Megan Reiter of Rice University took her colleagues on a “deep dive” through the Cosmic Cliffs, a cloudy hotbed of star formation in the Carina constellation, which was a favorite early piece of sky candy. She is tracing how jets from new stars, shock waves and ionizing radiation from more massive nearby stars that were born boiling hot are constantly reshaping the cosmic geography and triggering the formation of new stars.

“This could be a template for what our own sun went through when it was formed,” Dr. Reiter said in an interview.
