A "buy two, get one free" deal on supermassive black holes at NGC 6240.
SN 1987A has puzzled astronomers for decades now. First spotted in 1987, the supernova never revealed its remnant neutron star. Until now.
The photo captured via the Hubble telescope depicts a galaxy, dubbed UGC 1810, engaged in a "titanic battle" with multiple star systems.
An international research team led by scientists from Göttingen and Potsdam proved for the first time that the galaxy NGC 6240 contains three supermassive black holes. The unique observations, published in the journal Astronomy & Astrophysics, show the black holes close to each other in the core of the galaxy. The study points to simultaneous merging processes during the formation of the largest galaxies in the universe.

Northwestern University researchers have developed a new thin, wireless system that adds a sense of touch to any virtual reality (VR) experience. Not only does this platform potentially add new dimensions to our long-distance relationships and entertainment, the technology also provides prosthetics with sensory feedback and imparts telemedicine with a human touch.
When it comes to electronics, bigger usually isn't better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in a wireless 'internet of things.' To make the devices small and comfortable enough to wear, scientists need to miniaturize their components. Now, researchers in ACS Nano have made the tiniest radio-frequency antennas reported yet, with thicknesses of about 1/100 of a human hair.
The gas turbines powering aircraft engines rely on ceramic coatings that ensure structural stability at high temperatures. But these coatings don't control heat radiation, limiting the performance of the engine.

As an alternative to the depletion of fossil resources, the reduction of CO2 emitted from fossil fuel combustion into valuable chemicals and fuel has drawn increasing attention. Due to the highly thermodynamic stability of CO2, it is still very challenging to find a sustainable and cost-efficient route to selectively convert inert CO2 at a high conversion rate under mild conditions. The water could also be a significant factor governing the reaction mechanism. On the one hand, water is one produ

Two pathways diverged in a chemical synthesis, and one molecule took them both. Chemists at the University of Tokyo have studied how molecular building blocks can either form a spherical cage or an ultrathin sheet that shows some of the basic properties of a "smart" material that can respond to its environment.
A recent study compared the reaction mechanisms of CO2 hydrogenation over the stepped Cu(211) surface in the absence and presence of water by microkinetic simulations. The water on each hydrogenation step and the whole activity and selectivity could kinetically accelerate the hydrogenation on CO2 to COOH, promoting the reverse water gas shift reaction to produce CO, but hardly influences the CO2 hydrogenation to methanol kinetically. High initial partial pressure of water thermodynamically inhi
The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes 3He and 4He.

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
Special light beams can be used to manipulate molecules or small biological particles. However, these optical tweezers only work with objects in empty space. Any disturbing environment would deflect the light waves and destroy the effect. This is a problem, in particular with biological samples. Now, a special method was developed to calculate the perfect wave form to manipulate small particles in the presence of a disordered environment, even if they cannot be touched directly.
In physics, anything that isn't forbidden must occur. So why don't the strong interactions violate CP-symmetry?
The secrets of dark matter could possibly be explained by antimatter particles - doppelgangers of matter particles that have the opposite electric charge.
Could the profound mysteries of antimatter and dark matter be linked? Thinking that they might be, scientists from the international BASE collaboration, led by Stefan Ulmer of the RIKEN Cluster for Pioneering Research, and collaborators have performed the first laboratory experiments to determine whether a slightly different way in which matter and antimatter interact with dark matter might be a key to solving both mysteries.
A study that takes a novel approach to the search for dark matter has been performed by the BASE Collaboration at CERN working together with a team at the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU). For the first time the researchers are exploring how dark matter influences antimatter instead of standard matter.
A new paper asks: What if antimatter is the portal into the dark universe?

An international research collaboration from Poland, the UK and Russia has created a two-dimensional system -- a thin optical cavity filled with liquid crystal -- in which they trapped photons. As the properties of the cavity were modified by an external voltage, the photons behaved like massive quasiparticles endowed with a magnetic moment, called 'spin', under the influence of an artificial magnetic field. The research has been published in Science on Friday, Nov. 8, 2019.
Cosmic rays are particles from outer space, typically protons, travelling at almost the speed of light. When the most energetic of these particles strike the atmosphere of our planet, they interact with atomic nuclei in the atmosphere and produce cascades of secondary particles that shower down to the Earth's surface. These extensive air showers, as they are known, are similar to the cascades of particles that are created in collisions inside particle colliders such as CERN's Large Hadron Collid
