In approximately 5 billion years, the sun will deplete its hydrogen fuel and collapse under its own gravity, becoming a white dwarf. Though Earth-sized, this dense remnant will retain much of the sun’s gravitational influence.

In the distant past, the solar system was rife with impacts and collisions. Millions of rocky objects zoomed chaotically through the system, smashing into each other in collisional cascades. Over time, many of them eventually became part of the rocky planets. What’s left of the space rocks are mostly gathered in the main asteroid belt.
A novel imaging technique used for the first time on a ground-based telescope has helped a UCLA-led team of astronomers to achieve the sharpest-ever measurement of a star’s surrounding disk, revealing previously unseen structure.
As far as particles of light are concerned, the collective is more important than the individual. When they get to decide between two states, they will favor the one that many of their fellow particles have already adopted. However, this collectivist tendency does not kick in until enough photons have assembled in the same place.
A new imaging system could help us see deeper into the universe than ever before. The same powerful technology could also help us analyze the chemical makeup of everyday materials such as food and medicines much faster and with greater accuracy than current methods.
Quantum researchers in the twenty-first century are part of an international network that requires a great deal of interaction and communication. Around one hundred publications on the topic are produced every day, often by authors who work in close collaboration with one another. New developments and discoveries are quickly integrated into the field, usually within a matter of just a few weeks. Researchers immediately proceed to build on these findings with innovative ideas. That is what the day-to-day life in the field of quantum theory looks like as it celebrates the one-hundredth anniversary of the initial development of quantum mechanics.
While the Charlotte-Mecklenburg Police Department’s quarterly report showed a drop in crime, officials expressed frustration that 60% of arrests for violent crimes were repeat offenders
The former Madera County deputy was being arrested by Fresno police when he resisted and was tased; he was taken to a hospital, where he attacked an officer and took his gun
Scientists have released a new study on the arXiv preprint server that catalogs the universe by mapping huge clusters of galaxies.
A radio pulsar is like a cosmic lighthouse, a highly dense, rapidly rotating star that emits beams of radio waves. If Earth happens to be in the path, a “pulse” of radio waves will be detected.
Very early on in our universe, when it was a seething hot cauldron of energy, particles made of matter and antimatter bubbled into existence in equal proportions. For example, negatively charged electrons were created in the same numbers as their antimatter siblings, positively charged positrons. When the two particles combined, they canceled each other out.
Around the world, research is advancing to efficiently confine fusion plasma and harness its immense energy for power generation. However, it is known that turbulence occurring at various scales within the plasma causes the release of plasma energy and constituent particles, degrading the confinement performance.
University of Houston researchers have made a discovery in thermal conductivity that overturns an existing theory that boron arsenide (BAs) couldn’t compete with the heat conduction of a diamond.
Researchers have uncovered ‘giant’ hand axes believed to date back between 200,000 and 300,000 years. It is believed the hand axes were used by a mysterious human ancestor to cut prey in prehistoric Europe, report experts. The ‘giant’ tools were used by ancient man to process hard materials such as wood and carcasses and were discovered at an archaeological site at Proto Maior in Spain. Furthermore, a recent study carried out on the giant hand axes, suggests that there may have been two species of ancient humans, who lived close to each other for long periods of time.  One group used technologies recently imported from Africa, while the others were long-standing residents. In Porto Maior, located in Galicia, a group of archaeologists, led by experts from the National Center for Human Evolution Research, have found an important repository of large tools dating back nearly 300,000 years. The tools have a distinctive style known as Acheulian, which is seen much more frequently in Africa and the Middle East than in Europe. The nature of the finding suggests that humans may have used these tools to cross the Mediterranean 300,000 years ago, but we have no idea how. It also shows that the Acheulean style coexisted for a long period of time with another style of tools, most likely belonging to a different species of primitive humans. The conclusions, recently published in the journal Scientific Reports, point out that although similar tools had already been found in southwestern Europe, they had never been found in this amount. Experts have recovered a total of 159 pieces, with a weight of 118 kilograms. The pieces are larger and heavier than those found in other parts of Europe, while they are consistent with those of other continents. ‘Porto Maior introduces further complexity to this overlapping technological pattern, and suggests that distinct early human populations of different geographical origins coexisted during the Middle Pleistocene (between 773,000 and 125,000 years ago)’, researchers, led by Dr. Martina Demuro, a research fellow at the University of Adelaide wrote in the Conversation. To explain this finding, two theories are currently considered by experts. The first involves an African population crossing the Mediterranean, while the second indicates an independent invention of a very similar style. The defenders of the second theory call attention to the subtle differences between the European findings and those of Africa. The authors of the study, on the other hand, are inclined towards the African option, arguing; “Any hypothetical reinvention of Acheulian technology in Europe would have occurred 1 million years after the appearance of Acheulean in Africa in a different environmental and technocultural context, and most likely by a human species that was very different from Homo ergaster, the species responsible for this technology.” “The discovery of Porto Maior is further evidence of the arrival of this technology from Africa, given the similarities that the site shares with deposits of African tools,” conclude experts.
