Solar Sails and Comet Tails: How Sunlight Pushes Stuff Around
It seems crazy, but light actually exerts a physical force on objects. It could power a new generation of spacecraft for deep-space missions......»»
An ambitious mission to Neptune could study both the planet and Triton
Mission concepts to the outer solar system are relatively common, as planetary scientists are increasingly frustrated by our lack of knowledge of the farthest planets. Neptune, the farthest known planet, was last visited by Voyager 2 in the 1980s......»»
Using sunlight to turn greenhouse gases into valuable chemicals
McGill University researchers have harnessed the power of sunlight to transform two of the most harmful greenhouse gases into valuable chemicals. The discovery could help combat climate change and provide a more sustainable way to produce certain ind.....»»

Earth to have new mini-moon for two months
A pair of asteroid dynamics researchers from Universidad Complutense de Madrid Ciudad Universitaria have found that a small asteroid will make one orbit around the Earth starting this month before departing back into other parts of the solar system......»»
JunoCam spots new volcano on active Io
A new volcano has been spotted on Jupiter's moon Io, the most geologically active place in the solar system. Analysis of the first close-up images of Io in over 25 years, captured by the JunoCam instrument on NASA's Juno mission, reveal the emergence.....»»
Daniel K. Inouye Solar Telescope produces its first magnetic field maps of the sun"s corona
The Daniel K. Inouye Solar Telescope, the world's most powerful solar telescope, operated by the NSF National Solar Observatory (NSO), achieved a major breakthrough in solar physics by successfully producing its first detailed maps of the sun's coron.....»»
Steering molecular twisting for hydrogen generation
Researchers from the Faculty of S&T at the University of Twente have developed a novel approach for the design of efficient solar fuel devices. Research performed by graduated Ph.D. student Kaijian Zhu shows that reducing the light-induced twisting o.....»»

Why are black holes stable against their own gravity?
Neutron stars are timelike matter with a maximum mass of about 2.34 solar masses in quantum chromodynamics (the strong color force). Black holes are spacelike matter that have no maximum mass, but a minimum mass of 2.35 solar masses. Indeed, black ho.....»»
Outer solar system is more populated than previously thought, research reveals
Survey observations using the Subaru Telescope's ultra-widefield prime focus camera have revealed that there may be a population of small bodies further out in the Kuiper Belt waiting to be discovered......»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»

Gigantic asteroid impact shifted the axis of solar system"s biggest moon, study finds
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher has realized that the solar system's biggest moon's axis has shifted as a result of the impact, which confirmed that the asteroid was around 20 t.....»»
Scientists develop multifunctional photocatalyst for wastewater treatment
Water contamination by pharmaceuticals and heavy metals poses severe environmental and health risks. Traditional methods like biodegradation and filtration often lack efficiency and sustainability. Photocatalysis, using solar energy to degrade pollut.....»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
