Scientists suggest using gold nanoparticle metasurfaces to determine substance molecular composition – Phys.org

A new method will make it possible to create compact devices that will accurately determine molecular composition of a liquid or gas, and help identify potentially dangerous chemical compounds. The results of the work carried out by researchers from ITMO Univ…

Most of the calcium in the universe – including the very calcium in our teeth and bones – was created in the last gasp of dying stars.
Called “calcium-rich supernovae,” these stellar explosions are so rare that astrophysicists have struggled to find and subsequently study them. The nature of these supernovae and their mechanism for creating calcium, therefore, have remained elusive.

Now a Northwestern University-led team has potentially uncovered the true nature of these ra…

SpaceX achieved a big win in their Starship spacecraft development program on Tuesday evening, flying the SN5 prototype of that future vehicle to a height of around 500 feet, propelled by a single Raptor engine. The test, which took place at SpaceX’s rocket development and testing facility in Boca Chica, Texas, marks the first time that a full-scale Starship prototype has left the ground.
The company released a video of the whole test, including footage captured both from a drone’s-eye-view, as…

Good news: Scientists have found the absolute best place on Earth
for romantic stargazing!
Bad news: It’s literally next-door to the South Pole.
The hotspot (or cold spot, in this case) is called Dome A, and is located on a plateau near central Antarctica
, roughly 2.5 miles, (4 kilometers) above sea-level. In a new study published July 29 in the journalNature
, researchers found that the conditions at Dome A are positively perfect for staring at the cosmos with minimal interference from E…
