Astronomers See Black Hole Jets Blaze 16x Wider Than The Full Moon in Our Sky

Posted by in category: cosmology

Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.

The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 million light-years away.

The black hole has a jaw-dropping mass of around 55 million Suns but isn’t visible in the image. It would be located within the small empty patch in the center of the two butterfly wing-like lobes.

Large helium nanodroplets splash like water upon surface collisions

Posted by in categories: nanotechnology, particle physics

While working with helium nanodroplets, scientists at the Department of Ion Physics and Applied Physics led by Fabio Zappa and Paul Scheier have come across a surprising phenomenon: When the ultracold droplets hit a hard surface, they behave like drops of water. Ions with which they were previously doped thus remain protected on impact and are not neutralized.

At the Department of Ion Physics and Applied Physics, Paul Scheier’s research group has been using nanodroplets to study ions with methods of mass spectrometry for around 15 years. Using a supersonic nozzle, tiny, superfluid helium nanodroplets can be produced with temperatures of less than one degree Kelvin. They can very effectively be doped with atoms and molecules. In the case of ionized droplets, the particles of interest are attached to the charges, which are then measured in the mass spectrometer. During their experiments, the scientists have now stumbled upon an interesting phenomenon that has fundamentally changed their work. “For us, this was a gamechanger,” says Fabio Zappa from the nano-bio-physics team. “Everything at our lab is now done with this newly discovered method.” The researchers have now published the results of their studies in Physical Review Letters.

Elon Musk’s SpaceX raises over $337 mln in fresh funding

Posted by in categories: Elon Musk, space travel

Dec 29 (Reuters) — Billionaire Elon Musk’s SpaceX has raised $337.4 million in equity financing, the rocket company disclosed in a regulatory filing on Wednesday.

SpaceX, which counts Alphabet Inc (GOOGL.O) and Fidelity Investments among its investors, hit $100 billion in valuation following a secondary share sale in October, according to CNBC. It had raised about $1.16 billion in equity financing in April.

SpaceX did not immediately respond to Reuters request for more details on the latest funding round.

Due to Precision Launch, NASA Says Webb Space Telescope’s Fuel Likely To Last Way More Than 10 Years

Posted by in categories: energy, space

After a successful launch of NASA’s James Webb Space Telescope Dec. 25, and completion of two mid-course correction maneuvers, the Webb team has analyzed its initial trajectory and determined the observatory should have enough propellant to allow support of science operations in orbit for significantly more than a 10-year science lifetime. (The minimum baseline for the mission is five years.)
