Each year, NASA's most venerable space telescope photographs the outer planets of the solar system.
And so this autumn, as usual, the Hubble Space Telescope turned to each planet in turn. The tradition allows astronomers to monitor how the atmospheres of these worlds — Jupiter , Saturn, Uranus and Neptune — change over time. But the photos are, of course, also stunning.
NASA Confirms Existence of Hundreds of New Worlds Outside Our Solar System
NASA has added hundreds of new confirmed exoplanets to its list of known worlds in deep space, significantly boosting the number of faraway planets we know about.
The total number of new confirmed exoplanets is 301, which marks a large increase to the total of 4,569 that scientists have already discovered.
The Solar System Is Full of Brines - The Atlantic
Ed Rivera-Valentín has spent quite a bit of time thinking about brines recently. The particular ratio of salt to water in the marinade. The special ingredients that can give things an extra kick.
But as with any good recipe, there's a balance, Daswani said. Too little salt and water could struggle to mingle with the other chemicals in the brine.
If Alien Probes are Already in the Solar System, Maybe we Could Detect Them Calling Home -
It’s been seventy years since physicist Enrico Fermi asked his famous question: “Where is everybody?” And yet, the tyranny of the Fermi Paradox is still with us and will continue to be until definitive evidence of Extraterrestrial Intelligence (ETI) is found.
In a recent study , two researchers from the University of Liège and the Massachusetts Institute of Technology (MIT) recommended that we look for evidence of transmissions from our Solar System.
NASA's DART mission will move an asteroid and change our relationship with the solar system |
The dinosaurs didn't have a space agency; maybe if they did they'd still be here, would-be planetary defenders sometimes quip about their quest to avoid an asteroid impact.
Planetary defense aims to identify any asteroids on track to cause serious damage to Earth and, should such a threat arise, act to deflect the rock. Such an impact is the only natural disaster that we can prevent, planetary defense experts often say.
A white dwarf star offers clues for the future of the solar system - Axios
A white dwarf star 1,300 light-years from Earth is blasting out radiation and ripping apart a companion in its orbit.
Why it matters: One day, scientists think the Sun will burn through its fuel and become a dense white dwarf. By learning more about this star, astronomers might be able to get a better sense of the future of our solar system.
Astronomers Find Scorching Hot Exoplanet Where a Year Lasts 16 Hours
Astronomers have discovered a blisteringly hot exoplanet that orbits its parent star in just 16 hours. At a distance of 1.5 million miles from its star, the planet has a "dayside" surface temperature of around 6000 F. This means the planet is as hot as some small stars.
The exoplanet, located 855 million light-years from Earth, is an example of a class of worlds called "hot Jupiters"—massive balls of gas comparable in size to the solar system's own gas giant, but which race around their parent stars, often completing an orbit in as short a period as under
Meet Leonard, a Visitor From Oort - The Provincetown Independent
As you read this, Comet Leonard is racing towards the Sun. It's visible before sunrise with binoculars and small telescopes, and there's a good chance it will become visible to the unaided eye in early December.
Comets are leftover bits from the formation of our solar system. They are giant dirty snowballs, typically 6 to 10 miles in diameter, composed of ice, dust, and rock. When the solar system was young, about 4.5 billion years ago, comets were everywhere.
Tracing Martian meteorites to the largest volcanic structure in the solar system
About a million years ago, an asteroid collided with the smooth surface of Mars. The collision released a cloud of debris and some of the rocky debris was dropped into the atmosphere, escaping the planet’s gravity to travel through the darkness of space.
Some of these rocks eventually found their way to Earth and survived diving through our planet’s atmosphere to crash to the surface – including a portion of seven pounds that crashed in Morocco in 2011.
