Zooming into the sun with Solar Orbiter
Solar Orbiter's latest images shows the full sun in unprecedented detail. They were taken on 7 March, when the spacecraft was crossing directly between the Earth and sun......»»
Scorching storms on distant worlds revealed in new detail
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study—the first of its kind—reveals the extreme atmospheric conditions on the celestial objects, which are swat.....»»
Nearby exoplanet could be first known ocean world: Webb telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope......»»
How astronomers work out the size of the solar system
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity and magnetism......»»
Nearby star cluster houses unusually large black hole
Fast-moving stars imply that there's an intermediate-mass black hole there. Enlarge / From left to right, zooming in from the globular cluster to the site of its black hole. (credit: ESA/Hubble & NASA, M. Häberle) Super.....»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Astronomers suggest up to 60% of near-Earth objects could be dark comets
Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a University o.....»»
Age data show planetesimals provided building materials for water-rich planets in the early solar system
Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These so-called planetesimals continually supplied building materials for planets—.....»»
NASA mission to study mysteries in the origin of solar radio waves
NASA's CubeSat Radio Interferometry Experiment, or CURIE, is scheduled to launch July 9, 2024, to investigate the unresolved origins of radio waves coming from the sun......»»
Painting roofs white helps lower city heat, studies say
White or reflective paint is more effective at cooling cities than covering roofs in solar panels or greenery, scientists say, and could offer some relief on extremely hot summer days......»»
NASA"s Parker Solar Probe completes 20th close approach to the sun
NASA's Parker Solar Probe completed its 20th close approach to the sun on June 30, 2024, matching its own distance record by coming about 4.51 million miles (7.26 million kilometers) from the solar surface......»»
Extreme Hail Storms Are Wrecking Solar Farms—but Defending Them May Be Easier Than It Seems
Climate change is making hail storms more intense, so designers have to find novel solutions to protect panels from expensive damage......»»
Honest dialogue is needed to help build consensus around solar radiation modification technology
Solar Radiation Modification (SRM) is a suite of possible technologies to counteract global warming by reflecting incoming solar radiation......»»
Cryovolcanism: Why study it? What can it teach us about finding life beyond Earth?
Universe Today has had the privilege of spending the last several months venturing into a multitude of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, plane.....»»
Researchers use AI to accelerate the chase for safer, better batteries
As the clean transition drives uptake of electric vehicles and energy storage for an electricity grid with ever greater dependence on variable renewable energy sources such as wind and solar, the danger from battery fires grows as well. To limit this.....»»
Abandoned farmlands could play a role in fighting climate change. A study shows exactly where they are
Farmland is often a battleground in the fight against climate change. Solar panels and energy crops are pitted against food production, while well-intended policy choices can create incentives for farmers to till up new lands, releasing even more hea.....»»
Novel material shows potential to produce green hydrogen
An article published in the journal Polymer describes the production of a material with the potential to be used to obtain hydrogen (H2) by solar-driven water splitting (photoelectrocatalysis) instead of the conventional electricity-driven process......»»
Climate and health benefits of wind and solar dwarf all subsidies
By displacing fossil fuels, wind and solar saved the US $250 billion over 4 years. Enlarge (credit: Ashley Cooper) When used to generate power or move vehicles, fossil fuels kill people. Particulates and ozone resulting.....»»
Novel carbon nanotube yarns can generate electricity from waste heat
In line with global efforts towards sustainability, the development of energy harvesting technologies has become a top research priority. Although renewable energy sources like wind and solar power have recently taken the spotlight, waste heat also s.....»»
Mystery of "slow" solar wind unveiled by Solar Orbiter mission
Scientists have come a step closer to identifying the mysterious origins of the "slow" solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the sun......»»
