A galactic ‘conspiracy’ disproven: Dark matter and stars not interacting as previously thought

A longstanding ‘conspiracy’ in astronomy—that stars and dark matter are interacting in inexplicable ways—has been overturned by an international team of astronomers, in a paper in Monthly Notices of the Royal Astronomical Society.

Astronomers explore the properties of quasar 1604+159

Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, including its morphology and magnetic field.

Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid

The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions.

Here Are NASA’s Unreleased Apollo Mission Images They Don’t Want You To See

The idea that NASA has encountered Alien life during the Apollo missions has aroused the curiosity of thousands of experts in the field for decades.

Ever since NASA successfully landed on the moon, people have wondered whether or not the astronauts on the lunar surface—and during their trip to the moon—witnessed things they couldn’t […]

Rocket engine explodes during test at UK spaceport

A rocket engine exploded during a test launch at Britain’s new spaceport in northern Scotland, officials said Tuesday, in a setback for the UK’s fledgling space sector.

Exoplanets may contain more water than previously thought

We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our solar system.

Specialized materials could passively control the internal temperature of space habitats

Areas of space have wildly different temperatures depending on whether they are directly in sunlight or not. For example, temperatures on the moon can range from 121 °C during the lunar “day” (which lasts for two weeks), then drop down to -133 °C at night, encompassing a 250 °C swing.

Project Helianthus—a solar-sail-driven geomagnetic storm tracker

Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the sun ramps into another solar cycle, those storms will become more and more common, and the dangers they present to Earth’s infrastructure will continue to increase.

Ocean salinity affects Earth’s climate—how about on exoplanets?

There’s a link between Earth’s ocean salinity and its climate. Salinity can have a dramatic effect on the climate of any Earth-like planet orbiting a sun-like star. But what about exoplanets around M-dwarfs?

Mapping Martian meteorites: Tracing origins on the red planet

Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They’ve traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. Their study was published recently in the journal Science Advances.

Ultrathin quantum light sources: Scientists show excitonic interactions boost efficiency of entangled photon generation

Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources.
