Elon will win.
The world’s two richest men are duking it out before U.S. regulators over celestial real estate for their satellite fleets.
Mars is on the outer boundary of our solar system’s habitable zone, meaning it’s a region where liquid water could form and exist for long periods of time. We know that water is the source of life on Earth, but could it also point to the same on Mars?

Curiosity about how well our bodies are ageing has fuelled an industry around telomere length tests, but the much touted “biological clock” in our DNA isn’t what we thought.

“Scientists found that a caterpillar called the tomato fruit worm not only chomps on tomatoes and their leaves, but also deposits enzyme-laden saliva on the plant, interfering with its ability to cry for help. If it all sounds a bit improbable, starting with the concept of plants crying for help, scientists also scoffed at that idea when it was first proposed a few decades ago. But it has been shown time and time again that when under attack, plants can emit chemical distress signals, causing their peers to mount some sort of defense. A classic example is the smell of a freshly mown lawn, which prompts the release of protective compounds in nearby blades of grass that have yet to be cut. In some cases, plant distress signals can even summon help from other species. That’s what happens with the tomato. When caterpillars nibble on the plant’s leaves, the leaf pores release volatile chemicals that are detected by a type of parasite: a wasp that lays eggs inside caterpillars. (Not to overwork the horror-movie analogy, but as with the hapless astronauts in the “Aliens” franchise, it doesn’t end well for the caterpillar.)”
While there’s a famous horror-movie spoof about killer tomatoes, no one seems to have made one about caterpillars—the insect pests that eat the juicy red fruits of summer.
A new theoretical study has proposed a novel mechanism for the creation of supermassive black holes from dark matter. The international team find that rather than the conventional formation scenarios involving ‘normal’ matter, supermassive black holes could instead form directly from dark matter in high density regions in the centers of galaxies. The result has key implications for cosmology in the early Universe, and is published in Monthly Notices of the Royal Astronomical Society.
A high-intensity accelerator beam is formed of trillions of particles that race at lightning speeds down a system of powerful magnets and high-energy superconductors. Calculating the physics of the beam is so complex that not even the fastest supercomputers can keep up.
A team of astronomers has discovered evidence of lightless hydrogen “snow clouds” that may make up much of the “missing” matter in the Milky Way.
According to our friends at the 45th Weather Squadron, there is a 90 percent chance of a go for launch.
