The James Webb Space Telescope: Looking back towards the beginning of time

In 1990, NASA launched the Hubble Space Telescope. It had faced years of delays and cost overruns, but it proved the existence of black holes, calculated the age of the universe, and delivered astonishing views of deep space.
But now, NASA has built something 100 times more powerful, capable of seeing stars so distant, their light has been traveling for nearly 14 billion years, since just after the Big Bang. It's the most ambitious, complex space observatory ever built: the James Webb Space Telescope. And it's scheduled to lift off in 10 days.
Scott Willoughby works for Northrup Grumman (which NASA hired to do most of the design and construction), and is the Webb's program manager. "It's got seven times the collecting area, a mirror which collects more light, to see things that are either dimmer or further away," Willoughby explained.
On May 7, health influencer Paul Saladino, M.D.. posted a video to his X account that promoted feeding "raw dairy" to infants. The post received over 90,000 views and sparked strong backlash before it was removed the following day. Saladino regularly advocates for "animal-based" diets featuring raw milk, including on his TikTok channel where he has over half a million followers.
Everywhere you look, things are getting more complicated. Our phones have over a thousand settings. Showerheads come with apps. Cars have touchscreens. Ovens have touchscreens. "There's no doubt that 'featuritis' is real," said design consultant Jakob Nielsen. "Most of these things are too complicated."
New research is adding to the evidence linking ultra-processed foods to health concerns. The study tracked people's habits over 30 years and found those who reported eating more of certain ultra-processed foods had a slightly higher risk of death — with four categories of foods found to be the biggest culprits.
