NASA’s Hubble traces dark matter in dwarf galaxy using stellar motions

The qualities and behavior of dark matter, the invisible “glue” of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it’s relevant to a galaxy’s evolution.

Physicists suggest tachyons can be reconciled with the special theory of relativity

Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles, are the “enfant terrible” of modern physics. Until recently, they were generally regarded as entities that did not fit into the special theory of relativity.

Theoretical physicists find Higgs boson does not seem to contain any harbingers of new physics

The Higgs boson was discovered in the detectors of the Large Hadron Collider a dozen or so years ago. It has proved to be a particle so difficult to produce and observe that, despite the passage of time, its properties are still not known with satisfactory accuracy. Now we know a little more about its […]

Modeling a right royal butterfly effect

The monarch butterfly, Danaus plexippus, is renowned for its striking appearance and perhaps even more than that, its remarkable long-distance migration. The population present in North America heads south each year in the late-summer, early autumn, traveling thousands of miles to its wintering grounds.

Understanding the origin of superconductivity in high-temperature copper oxide superconductors

Superconductors are materials that can conduct electricity with zero resistance when cooled to a certain temperature, called the critical temperature. They have applications in many fields, including power grids, maglev trains, and medical imaging. High-temperature superconductors, which have critical temperatures higher than normal superconductors have significant potential for advancing these technologies. However, the mechanisms behind […]

JWST sheds light on the structure of interstellar water ice

Using the James Webb Space Telescope (JWST), a team of researchers including Paola Caselli, Barbara Michela Giuliano and Basile Husquinet from MPE, have probed deep into dense cloud cores, revealing details of interstellar ice that were previously unobservable. The study, published in the journal Nature Astronomy, focuses on the Chamaeleon I region, using JWST’s NIRCam […]

Nearest millisecond pulsar has radius of 11.4 kilometers and is 1.4x as heavy as the sun, researchers find

The nearest millisecond pulsar PSR J0437-4715 has a radius of 11.4 kilometers and a mass 1.4 times that of the sun. These are the results of precision measurements made by a team of researchers led by the University of Amsterdam (the Netherlands). The measurements reveal more about the composition and magnetic field of this neutron […]

Physicists demonstrate quantum scale inverse Mpemba effect with single trapped ions

A team of physicists at the Weizmann Institute of Science in Israel has successfully demonstrated the inverse Mpemba effect at the quantum level using single trapped ions. In their study, published in the journal Physical Review Letters, the group demonstrated the effect by trapping a strontium-88 ion coupled to an external thermal bath.

European researchers reach unmatched level in measurements of matter under extreme conditions

Researchers at European XFEL have developed an innovative method to study warm dense matter with unprecedented accuracy. This kind of matter, that exists between condensed matter and plasma physics, can be found, for example, in astrophysical objects or is created during inertial confinement fusion.

Astronomers apply machine learning techniques to find early-universe quasars in an ocean of data

Quasars are extremely luminous galactic cores where gas and dust falling into a central supermassive black hole emit enormous amounts of light. Due to their exceptional brightness, these objects can be seen at high redshifts, i.e., large distances.

A massive, mysterious Hole has just opened up in Antarctica and experts cant explain it

A massive, mysterious Hole has just opened up on the surface of Antarctica leaving experts confused as they are unable to explain what caused its formation.

The hole—as large as lake superior or the state of Maine, with an approximate area of 30,000 square mile—has created confusion among experts, who are unable to explain […]
