Sirius (Alpha Canis Majoris) Facts: Star System, Location, Constellation

Posted by in categories: energy, space

Essentially based on myth the sirius cat people live here. O,.,o.


Sirius, Alpha Canis Majoris (α CMa), is the brightest star in the night sky and one of the nearest star systems to Earth. It has an apparent magnitude of −1.46 and lies at a distance of only 8.6 light years from the Sun. It is also known as the Dog Star, in reference to its position as the luminary of the constellation Canis Major, the Greater Dog.

Sirius appears so bright both because it is intrinsically luminous, with an energy output about 25.4 times that of the Sun, and because of its proximity to the solar system. However, compared to other bright stars like Rigel (120,000 solar luminosities), Betelgeuse (90,000 to 150,000 L) and Canopus (10,700 L), or even Arcturus (170 L) and Capella (78.7 L), Sirius is not exceptionally bright.

Listening to quantum radio

Posted by in categories: biotech/medical, quantum physics, space

Circa 2019


Researchers at Delft University of Technology have created a quantum circuit to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas such as radio astronomy and medicine (MRI). It also enables experiments to shed light on the interplay between quantum mechanics and gravity. The results have been published in Science.

The usual solution to a weak radio signal is to find a bigger signal, for instance, by picking a different radio station or by moving to the other side of the room. However, m what if we could just listen more carefully?

Antares launch scrubbed due to faulty ground support equipment

Posted by in categories: military, space

The military-run spaceport at Cape Canaveral will soon be renamed Cape Canaveral Space Force Station to reflect the facility’s transition from the U.S. Air Force to the newly-created Space Force, military officials said Friday.

Officials said Cape Canaveral Air Force Station, home operational launch pads leased by United Launch Alliance and SpaceX, and nearby Patrick Air Force Base south of Cocoa Beach, Florida, will both get new names.

Brig. Gen. Doug Schiess, commander of the 45th Space Wing which oversees Patrick Air Force Base and Cape Canaveral Air Force Station, said Friday that the two installations on the Space Coast will be among the first military facilities in the country receiving new names after the creation of the Space Force in December.

Eyes to the skies: Rocket launch to be visible in DC region

Posted by in categories: space, transportation

NASA Wallops Flight Facility is scheduled to launch a rocket tonight that will be visible to the DMV as it climbs into the sunset sky.

The facility hopes to launch the 13th Northrop Grumman resupply mission to the International Space Station (ISS) at 5:39 p.m. near sunset. The Cygnus cargo ship (spacecraft) is the S.S. Robert H. Lawrence, named for the first ever African American selected as an astronaut.

The launch and mission will be carried live by NASA.

Beyond Infinity: An Expedition to the Outer Limits of Mathematics

Posted by in categories: mathematics, space

O.o!


A mind-expanding and funny trip to the edge of mathematics

How big is the universe? How many numbers are there? And is infinity + 1 is the same as 1 + infinity? Such questions occur to young children and our greatest minds. And they are all the same question: What is infinity? In Beyond Infinity, Eugenia Cheng takes us on a staggering journey from elemental math to its loftiest abstractions. Along the way, she considers how to use a chessboard to plan a worldwide dinner party, how to make a chicken-sandwich sandwich, and how to create infinite cookies from a finite ball of dough. Beyond Infinity shows how one little symbol holds the biggest idea of all.
