The huge “dog-boned” asteroid hurling through the solar system has now been imaged in unprecedented detail.
A team of astronomers has seemingly obtained the best pictures and data to date of the peculiar asteroid, Kleopatra. Using the European Southern Observatory’s Very Large Telescope (VLT), observers from the SETI Institute in Mountain View, California, and the Laboratoire d’Astrophysique de Marseille, France, captured images to help two teams of scientists answer some interesting questions.
“Kleopatra is truly a unique body in our Solar System,” says Franck Marchis, who led a study on the asteroid published in Astronomy & Astrophysics. “Science makes a lot of progress thanks to the study of weird outliers. I think Kleopatra is one of those and understanding this complex, multiple asteroid system can help us learn more about our Solar System.”
The asteroid, which orbits in the central region of the asteroid belt between Mars and Jupiter, was initially discovered on April 10 1880. However, it wasn’t until just 20 years ago that radar observations revealed it had two lobes which were connected by a thick “neck.” In 2,008 Marchis and his colleagues discovered that the asteroid was orbited by two moons, named AlexHelios and CleoSelene, after the Egyptian queen’s children.
Optical lattice clocks could help scientists detect gravitational waves, hunt for dark matter and much more.
Two physicists just snagged $3 million for helping develop a super-precise clock that could allow scientists to study and explore the universe like never before.
Researchers at the University of California, Berkeley have outlined details of an optical antenna they claim could provide almost limitless bandwidth.
They suggest the key to the breakthrough is a method of being able to take full advantage of the orbital angular momentum (OAM) properties of a coherent light source, thus enabling multiplexing, or simultaneous transmission.
According to Boubacar Kante, the principal investigator of the Berkeley project “it is the first time that lasers producing twisted light have been directly multiplexed.” He is an associate professor in the university’s Electronic Engineering and Computer Sciences Department, and the initial results of the work have just been published in Nature Physics.

HOUSTON – (Sept. 1 2021) – Rice physicists have confirmed the topological origins of magnons, magnetic features they discovered three years ago in a 2D material that could prove useful for encoding information in the spins of electrons.
The Moon’s lack of atmosphere and darkness could offers unique observations of the universe.

This video’s topic is close to my own research, cosmology. The current standard model of cosmology rests on the “cosmological principle” — the idea that the universe looks, on the average, the same everywhere. Alas, it doesn’t look good for the cosmological principle. Just what does the evidence say and, if it holds up, what does this mean? At the end of this video, you’ll know.

Scientists recently broke their own laser-fusion record! But they must replicate their success soon to preserve research in thermonuclear weapons.
