Even in our cosmic backyard, the Solar System, many questions remain open. On Venus there are formations similar to volcanoes, but it is not known if they are active. The surface of Mars suggests that there was once a vast ocean, but how it disappeared remains unclear.
Scientists Think Solar Storms Will Knock Out Internet And Electrical Systems
Back in 1859, long before the internet, a massive geoelectrical storm knocked out the telegraph systems in the world. Reports were given of telegraph operators being shocked, the paper catching fire, and the equipment being operated without the batteries being connected.
The Carrington Event was the largest recorded geoelectrical storm, but it wasn’t the first to happen. An even bigger storm happened in our solar system in A.D. 774, based on readings taken from ice core samples in the Antarctic.
Asteroid Ryugu may be a remnant of an extinct comet | Space
Observations from Japan's Hayabusa2 mission have astronomers questioning the true origin of the near-Earth asteroid Ryugu.
The remote observations suggest that rather than a single, monolithic boulder, Ryugu is a rubble-pile asteroid composed of small pieces of rock and solid material clumped together by gravity , researchers reported in a recent study.
Saturn Is Currently Eating Its Own Rings, The Standout Feature Of Our Solar System
The allure of Saturn for Earthlings lies in the planet's gorgeous rings that encircle the gas giant, giving it a unique look in our solar system. Now, it seems that Saturn is slowly losing its rings... to itself . Yep, you read that right! Saturn is currently nibbling on its rings.
Oliver Jeffers on bringing solar system down to Earth for Our Place in Space - The Irish News
Our Place in Space brings our solar system to ground level
"THIS project is not a scale model of Earth's place in the solar system," explains Oliver Jeffers, "it's a scale model of humanity's place within the solar system."
The Australian-born, Belfast-raised artist and children's author is talking to me about Our Place in Space , perhaps his most ambitious project to date: a 10km-long scale model of our solar system that will appear in Derry later this month as part of the Unboxed: Creativity in the UK ...
For Our Place in Space, Oliver Jeffers talks about bringing the solar system to Earth. - Bollyinside
"THIS project is not a scale model of Earth's place in the solar system; it is a scale model of humanity's role within the solar system," says Oliver Jeffers.
The Australian-born, Belfast-raised artist and children's author is speaking with me about Our Place in Space, perhaps his most ambitious project to date: a 10-kilometer-long scale model of our solar system that will be unveiled in Derry later this month as part of the Unboxed: Creativity in the ...
Ten Years Hence lecture explores possible trillion-dollar asteroid mining industry // The Observer
"What we want to do is get water from the moon or from asteroids, use the water to fuel the spacecraft which we then sell to customers," Jedicke said.
Jedicke said he has been working with asteroids and comets for over 30 years. However, he wasn't introduced to the asteroid mining industry until about 10 years ago.
EarthSky | Background glow of the universe is oddly bright
We might think of space as an unending void of pitch black darkness, punctuated only by tiny lights of stars and distant galaxies. But is it really that dark? Not quite! There’s a small but significant amount of background light that permeates the visible universe.
About half the amount of background light – called the cosmic optical background ( COB ) – can be accounted for by the usual stars and galaxies. But the other half is a bit mysterious. Where does this extra light come from?
5 planets will be visible in the sky in April - here's when you can watch them
Earth will be graced with a springtime planetary parade of five planets throughout April 2022. Astronomers will have multiple chances to spot Venus, Mercury, Mars, Jupiter, Saturn, and Uranus in the sky.
This isn’t the first time we’ve seen planets like Venus visible from the Earth . It is, however, a welcome event that budding astronomers will want to take advantage of.
