A star in a galaxy passes by a black hole closely enough to be destroyed once every 10,000 years. It is possible to detect the death of a star in a fairly distant galaxyas the destruction of a star generates a bright X-ray flare; it is only necessary to distinguish such a flare from other types of X-ray radiation. Because flares occur in a variety of astrophysical processes, the task of finding stars destroyed by black holes is quite complicated. (Credit: Sergei Sazonov)

Some of the best evidence for parallel worlds actually arrives courtesy of an enigmatic oddity within deep-space, careening toward the Milky Way at an incredible 200,000 miles per hour. Though it’s more than 2 million light years away, the Andromeda galaxy, appears to engage in anomalous behavior which suggests a strange gravitational phenomenon. Specifically, gravity that could be draining from another universe, as yet invisible to us, could be the impetus behind such anomalous phenomena. (Credit: Micah Hanks)

Having a single point in contact with the ground lets a ballerina spin. In the same way, a quantum state is dynamic because it can turn about a point thanks to quantum uncertainty, say CQT and Oxford researchers. (Credit: Michael Garner, courtesy English National Ballet)

In Einstein’s general theory of relativity, gravity is nothing more than the curvature of spacetime. A massive object, such as the sun, causes a deformation of the spacetime grid, while another object such as a planet or a light beam follows the shortest path (a “geodesic”) on this grid. To an observer, this looks like a deflection of the trajectory caused by gravity. (Bottom) A collapsing star can form a black hole so dense and massive that it creates a region of infinite curvature (a “singularity”) so that—inside the event horizon—light cannot escape. Current research in gravitation is attempting to modify general relativity to account for such objects consistent with quantum theory. (Credit: Carin Cain)

Shown above is part of one of the most imaged parts of the night sky, the Orion Nebula. Since the angular size of Orion’s Nebula is so large on the sky, only a portion is shown here. Located just below “Orion’s Belt” this star-forming region is dominated by four young, massive O stars (known as the Trapezium, not pictured here). The wispy blue, green gas seen above is composed mostly of hydrogen, the main element used in forming stars. The Orion Nebula is an astrophysical laboratory, providing an up-close view of the birth of stars. (Credit: Sloan Digital Sky Survey)

To celebrate the NASA-ESA Hubble Space Telescopes 16 years of success, NASA and the European Space Agency are releasing this mosaic image of the starburst galaxy, Messier 82 (M82), made in March 2006. It is the sharpest wide-angle view ever obtained of M82, a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions. Located 12 million light-years away, it is also called the “Cigar Galaxy” because of the elongated elliptical shape produced by the tilt of its starry disk relative to our line of sight. (AP Photo/NASA-ESA)
This image of the galaxy Messier 82 is a composite of data from the Chandra X-Ray Observatory, the Hubble Space Telescope and the Spitzer Space Telescope. The intermediate-mass black hole M82 X-1 is the brightest object in the inset, at approximately 2 o’clock near the galaxy’s center. (Credit: NASA/H. Feng et al.)

Every once in a while I think that there maybe is no fundamentally smallest unit of length; that all these arguments for its existence are wrong. I like to think that we can look infinitely close into structures and will never find a final theory, turtles upon turtles, or that structures are ultimately self-similar and repeat.(Credit: Sabine Hossenfelder, Sanghyuk Moon)

NIST researcher Kevin Dwyer with the silicon enrichment apparatus. The process begins at the left, where natural-abundance silicon in the form of silane gas (SiH4) is ionized. The ions pass through a magnetic field (top left), which causes their paths to curve to different degrees based on their mass. The silicon-28 ions, now separated from the other silicon isotopes, are decelerated through an ultra-high vacuum chamber (top center) and into the deposition chamber (top right) (Credit: Pomeroy, NIST, Dwyer)

A protein folding funnel, the product of algorithms created by Rice’s Center for Theoretical Biological Physics, is a graphic representation of the energy landscape a protein navigates as it goes from its initial floppy state to a folded, functional unit. The funnel shows smooth slopes as well as outcroppings where parts of a protein may pause while others catch up, and also traps that could cause a protein to misfold. New Rice research shows how the interplay between evolution and physics developed the skills necessary to conserve useful proteins. (Credit: Center for Theoretical Biological Physics/Rice University)
