In the first four days of February this year the Sun unleashed six powerful X-class flares in rapid succession including an X8.1 that was the strongest in several years. And now, scientists have announced a new forecasting system that could give us up to a year's warning before the most dangerous solar storms arrive. The extraordinary thing is that the system has already been proved right by eruptions nobody knew about until after the forecast was made.
In 1950, the physicist Enrico Fermi sat down to lunch with colleagues and asked a question that has haunted astronomers ever since. If the universe is so vast, so old, and so full of stars, where is everybody? A new study has turned that question around and come up with an answer that is quietly unsettling. If intelligent life is common in the Galaxy, the mathematics suggests it cannot last very long.
The rocks that twelve astronauts carried home from the Moon fifty years ago have just rewritten our understanding of lunar history. A new analysis of Apollo samples has finally resolved one of the most stubborn debates in planetary science and the answer turns out to be one that neither side of the argument was entirely right about.
Editors of The Lancet published an op-ed decrying RFK Jr.'s one year of failure at HHS. They're correct about RFK Jr, but they are not blameless in what has happened.
The post One year of Robert F. Kennedy Jr. as HHS Secretary: The Lancet reacts, and so do I first appeared on Science-Based Medicine.Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.
They are the toughest animals on Earth and possibly the key to surviving on Mars. Tardigrades, the microscopic creatures nicknamed 'water bears', have survived the vacuum of space, the crushing pressure of the deep ocean and temperatures that would kill virtually anything else. Now a new study has put them to work as unlikely pioneers, testing whether the hostile soil of Mars could ever support life and the results are full of surprises.
A visitor from another star system has just had its portrait taken by a spacecraft on its way to Jupiter and the image is superb. Comet 3I/ATLAS, only the third interstellar object ever discovered passing through our Solar System, has been captured in stunning detail by ESA's JUICE mission, revealing a glowing halo of gas, a sweeping tail, and hints of jets erupting from its ancient, icy heart. But the picture itself is just the beginning of the story.
SpaceX's Starship is the most powerful rocket ever built and it may be about to change everything. But researchers at the German Aerospace Centre have been asking a question: does Europe have an answer? Their new study, built on meticulous analysis of Starship's own flight data, suggests the answer is yes although it will require a fundamentally different approach, and a willingness to think differently.
We’re back again with readers’ photos, but this is only one of two batches I have left. Please send ’em if you got good photos.
Today we have plants (and one video of flamingos), and different views of one species of plant from reader Eric Cabot. Eric’s captions are indented, and you can enlarge the photos by clicking on them. Following Wallace Stevens, I’d call this “Eleven Ways of Looking at a Lotus.”
Here is a series of photographs featuring the American Lotus (Nelumbo lutea), taken at a roadside pond in Middleton, Wisconsin, in mid-August, 2018 There are few things as comforting as a quiet boardwalk-stroll through a flotilla of this beautiful plant towards the end of a fine day.
I was unsure of the plants’ identity until I found this statement on an informative website (https://www.wisconsinwetlands.org/): Lotus leaves are circular but do not have a notch/sinus—they are continuous all the way around.
Unfortunately, the pond and the paths and boardwalks associated it were completely washed away by a deadly flash flood the following spring. The pond has since been rebuilt, but not the boardwalk. I haven’t gone back to see if the site has any lotuses. For now the images will have to do.
Here a video of pink flamingos the I recorded in “Cabo” a few years ago. [JAC: Keep watching for the displays and weird cries.]
