Ukrainians will be able to see in August a small parade of planets

The moon is visually closer to the four planets of the Solar system. In August, the spectacular convergence of the moon and four planets in the Solar system (Mars, Saturn, Neptune and Uranus) can be seen over the southern horizon. Visually, the Moon will pass in 2-7º from these planets. Best convergence will be seen […]

Sprawling galaxy cluster discovered 'hiding in plain sight'

Sprawling galaxy cluster discovered 'hiding in plain sight'

An X-ray image (in blue) with a zoom in optical image (gold and brown) showing the central galaxy of a hidden cluster, which harbors a supermassive black hole. (Image: Taweewat Somboonpanyakul) Scientists at MIT have discovered a galaxy cluster that they say is “hiding in plain sight.” Located just 2.4 billion light years from Earth, […]

Not just land heat waves: Oceans are in hot water, too

Not just land heat waves: Oceans are in hot water, too

Between 1982 and 2016, the number of “marine heat waves” roughly doubled, and likely will become more common and intense as the planet warms, a study released Wednesday found. Prolonged periods of extreme heat in the oceans can damage kelp forests and coral reefs, and harm fish and other marine life. Source link

High-energy protons emitted after hooking up with neutrons

High-energy protons emitted after hooking up with neutrons

Enlarge / Abstract image of electrons and protons. If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron stars. One of the unexpected things we seem to be learning is […]

Bam! Meteorite bombardment created Earth's oldest rocks

Bam! Meteorite bombardment created Earth's oldest rocks

Artist’s concept of the period in Earth’s early history, about 4 billion years ago, when meteorites bombarded our world. Image via Paleoblog. Scientists meeting in Boston this week at the Goldschmidt conference reported on 4.02-billion-year-old rocks from Acasta River, Canada, site of the world’s oldest exposed rocks. They presented results from a new computer modeling […]

Satellite Sees Double When Snapping Solar Eclipse Pictures from Space

Satellite Sees Double When Snapping Solar Eclipse Pictures from Space

A new image of a solar eclipse will have you seeing double. Views from the sun-watching Proba-2 satellite show the moon passing in front of the sun in two pictures snapped during a partial solar eclipse on Saturday (Aug. 11). The satellite flew through the moon’s shadow twice during the eclipse. Solar eclipses happen when […]

Super-insulating gel could help build Mars habitats

Super-insulating gel could help build Mars habitats

Washington, Aug 14 (PTI) Scientists have developed a transparent heat-resistant gel using beer waste that may one day be used to build greenhouse-like habitats for human colonised on Mars. The “aerogel,” which looks like a flattened plastic contact lens, could also be used on buildings on Earth to help make huge savings on energy costs. […]

Hothouse Earth: our planet has been here before – here's what it looked like

Hothouse Earth: our planet has been here before – here's what it looked like

Even if carbon emissions are reduced to hold temperature rises at the 2°C guardrail of the Paris Agreement, changes already afoot in the environment such as melting permafrost and forest die-back could accelerate warming well into the future, potentially pushing our planet into what is being called a “Hothouse Earth” state. The risk of a […]
