Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center -- a surprise suggesting our galaxy's gravitational core may have less dark matter than previously thought.

'Hidden' stars including a new type of elderly giant nicknamed an 'old smoker' have been spotted for the first time by astronomers. The mystery objects exist at the heart of our Milky Way galaxy and can sit quietly for decades -- fading almost to invisibility -- before suddenly puffing out clouds of smoke, according to a new study.

A new study describes the best method to improve images obtained by the James Webb Science Telescope (JWST) using a mathematical approach called deconvolution.

The microquasar SS 433 stands out as one of the most intriguing objects within our Milky Way. A pair of oppositely directed beams of plasma ('jets') spirals away perpendicularly from the binary systems disk's surface at just over a quarter of the speed of light. The H.E.S.S. observatory in Namibia has now succeeded in detecting very high energy gamma rays from the jets of SS 433, and identifying the exact location within the jets of one of the galaxy's most effective particle accelerators.

A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.

A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.

A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.

A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.

The behavior of specific weather patterns and their impact on power faults could be used to develop a weather pattern - conditioned fault forecasting system for power system operators.

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.

An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.

Female meadow brown butterflies have fewer spots if they develop in warmer weather -- so climate change could make them less spotty, new research shows.

A new study is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare.

Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.

Astronomers have discovered a planet closer and younger than any other Earth-sized world yet identified. It's a remarkably hot world whose proximity to our own planet and to a star like our sun mark it as a unique opportunity to study how planets evolve.
