“Either there is a missing ingredient in the simulations or we have made a fundamental incorrect assumption about the nature of dark matter,” Yale University astrophysicist Priyamvada Natarajan, a co-author of the study published in the journal Science, said on Friday.
The focal plane took six months to assemble. Each grid of nine sensors is called a scientific raft, and 25 rafts had to be fitted into their spots along the grid. The sensors can easily crack if they come in contact with each other, and they only have a tiny gap between rafts — less […]
The glimmers of light are visible even when they are near the edge of Ceres, suggesting that they must be high above the surface rather than at the bottom of an impact crater, as previously believed.
Controversial: He weighed in on his former series in an interview with PopCulture.com , admitting he hadn’t heard of the petition launched by upset fans, but said he ‘would sign it’
So, one of the ways astronomers can detect dark matter is through gravitational lensing, in which gravity essentially distorts space. This occurs when the gravity of dark matter in a galaxy cluster acts like a magnifying glass. It warps and magnifies the light of distant background galaxies beyond the cluster.
That all changed earlier this year when astronomers found that FRB 180916.J0158+65 had a pattern in bursts occurring every 16.35 days. Over the course of four days, the signal would release a burst or two each hour. Then, it would go silent for another 12 days.
McDowell, an astronomer at the Center for Astrophysics | Harvard & Smithsonian (CfA), stressed that we cannot assume the spacecraft is a space plane. “‘Reusable’ doesn’t necessarily mean ‘winged,’” he wrote on Twitter on Sunday. “Still could be a [SpaceX] Dragon-style capsule, with a parachute, landing in the Taklamakan somewhere. Exact launch and landing times […]
Blame! takes place in the distant future, where humanity largely struggles to survive in a perpetually growing city-structure filled with dangerous robots called safeguards. The sheer size of the city — no one actually knows how big it is — means small groups of people have evolved in isolation, rarely interacting with each other. Killy […]
The X-37B, resembling a miniature space shuttle, has been in orbit since late May following its launch on its sixth assignment. Very little is known about the X-37B’s missions, prompting speculation that the planes could be used for spying activity or testing space weapons.
For now, Brandon’s tests with the bacteria continue. “We’re still a little way off from doing it at scale,” she says, “but with our new research … we have developed a system that will enable us to move to this future a lot faster. Hopefully this will be a viable technology.”
