Astronomers have hunted for this planet since 2016. Could one more year of searching finally solve the mystery?
Researchers have dramatically narrowed down the possible location of the elusive Planet X, a massive, yet undiscovered member of our solar system.
It’s not the hypothesized giant Planet Nine
It will help scientists better understand interactions between solar and interstellar winds.
Astronomers have discovered iron and nickel vapour in the atmospheres of comets distant from the Sun and surrounding the interstellar visitor 2I/Borisov.
Astronomers have measured Jupiter's Stratospheric Winds for the First Time.
I am not making any of this up.
The melting of ice beneath the surface of Mars could have made its deep regions the most habitable.
The results from New Horizon's New Year's Day Flyby of Kuiper Belt Object Arrokoth are in, and it could just change how we think about planet formation.
The study of the Kuiper Belt body Arrokoth promises to change how we believe the building blocks of planets form. Thus revealing more about how planets such as the Earth are born.
NASA provides the ultimate hotfix.
New observations confirm that main asteroid belt object Hygiea is round. It now fulfills all the requirements to graduate from asteroid to dwarf planet.
The daring spacecraft traveled more than 11 billion miles to exit the solar system.
The solar system is very different from our own.
It also met a lot of asteroids it still hangs around with.
It's more than 100 times farther away than Earth is from the sun.
The small asteroid also seems to be emanating streams of gas that may explain why it was moving faster than it was supposed to.
The chances of it happening are pretty slim though.
The findings might revolutionize our understanding of how the solar system came to be, as well as all planetary bodies for that matter.
An elusive planet ten times more massive than Earth may be lurking in the outer fringes of the solar system.
Pieces of an ancient planet formed long before Earth shed their secrets.
A unique cosmic stone challenges what we know about how the solar system formed.
Put the kettle on, we have a visitor.
A ninth planet 10 times bigger than Earth might be lurking far away within the solar system.
This fatty likely had a great influence on how other later planets formed in the early solar system, including Earth.
It's all about the conservation of angular momentum.
Pluto and Ceres have a new neighbor.
A duo of astronomers from CalTech may have found another planet, far away in our solar system.
A new dwarf planet, designated V774104 has been identified and now takes the crown of most distant object in our solar system, being three times farther away than Pluto. The dwarf planet is estimated to be between 500 and 1000 kilometers across. Astronomers don't yet have enough data to estimate its orbit and estimate that about an year of observations is needed to gather enough data for a precise answer.
A new shocking theory suggests that Jupiter may have sweeped through our solar system much like a wrecking ball, knocking planets out of the solar system our moving them outwards, to the position we see them in today. If this is true, then it might explain why our solar system is a rarity and why life emerged the way it did.
Nibiru followers might have cause to rejoice, as Spanish astronomers report a novel hypothesis that suggests two Earth-sized planets might be hiding out in the outskirts of our solar system. Thousands of years after the first planets besides our own were discovered by ancient Babylonian astronomers, it seems like determining the number of planets in our solar is far from being settled, despite Pluto's unfortunate destitution.
For decades, astronomers have believed that meteorites are the building blocks of our solar system - the lego blocks for planets. But a new study from scientists at MIT and Purdue University suggests that this may not be the case after all - and we've given meteorites too much credit.
After studying ancient minerals in a meteorite, MIT scientists have gained valuable insights that help explain how the sun, the planets and our entire solar system formed.Their work suggest that a powerful shock wave that rippled through the clouds of dust and gas surrounding the sun billions of years ago played a crucial role in […]
We live in a solar system filled with water. Not only does liquid water cover 72% of our planet Earth, we have also found ice water in asteroids and comets, on the Moon, on Mars, and even in the shadows of craters on Mercury; while Europa and other moons of Jupiter and Saturn almost certainly […]
A new massive computer model that simulates the formation of the solar system from its early days when all it used to comprise was a huge disk of matter to present day shows that Earth’s moon formed some 65 million years later than previous estimates led us to believe. The method provides a new way […]
For the first time, researchers have found evidence of a comet entering Earth’s atmosphere and exploding, obliterating everything in its path before ultimately crashing down into the Sahara. Comets and asteroids Many people will probably be asking themselves “Didn’t we find comet evidence on Earth before?”. No, not really – if you did wondeer that, […]
To boldly go where no man has gone before: a spacecraft launched from Earth, Voyager I has pushed into the great unknown, leaving behind our solar system. For years, astronomers have been discussing about when Voyager will finally leave the solar system – and it’s actually pretty hard to draw a line and say that […]
Planetary scientist Kelsi Singer initially studied satellite photographs of Saturn’s icy moon Iapetus’ surface looking for stress fractures in the moon’s ice, what she found in process however was far more interesting. Huge landslides, stretching across tens of miles across the moon’s surface were observed, not in one, but multiple locations, hinting this is a common phenomenon […]
Astronomers have discovered a new moon orbiting the dwarf planet of Pluto – its fifth – only a year after the former planet’s forth satellite was discovered. In the past decade alone, four out of Pluto’s five moons known thus far have been discovered. The latest addition, provisionally titled S/2012 (134340) 1 or P5, is only between 6 […]
Our solar system is special for two reasons: the first one, obviously – is us. Our solar system is the only one we know of so far that hosts life. The second one is the number of planets – no other solar system that we’ve seen until now had as many planets as ours, but […]
Unexpected new findings from University of Maryland researchers show that a portion of our planet’s mantle survived Earth’s rough formation, including a collision with a planet-sized body which many believe led to the creation of the Moon, as we see it today. “It is believed that Earth grew to its current size by collisions of […]
Discovered deep in the farthest reaches of our solar system, Haumea is a tiny dwarf planet which has been fascinating scientists for years now since its discovery in 2004, not only because of its peculiar rugby-ball shaped form, but also because of its surface structure. According to the European Southern Observatory, 75 per cent of […]
Our solar system appears to exist inside a “bubble”, inside a network of cavities inside the interstellar medium, which was probably created by massive star explosions millions billions of years ago. Interstellar medium (ISM) is a term coined for the matter that exists in galaxies, between solar systems. This matter includes gas in ionic, atomic, […]
A probe that has been launched no less than 30 years ago has come across a force that has baffled the scientific world and could rewrite the laws of physics. In 1983, Pioneer 10 took some photos of Jupiter, then left the solar system. However, it’s being pulled back to the Sun by a force […]
There are many things we have yet to find out about Saturn, but the Cassini probe has definitely shed some light on the planet, and will surely do the same in the following years. The most recent flyby showed a significant number of geysers just waiting to pop out from under the surface – even […]
As I was writing in a previous post, Titan is quite unique, in that aside from our planet it’s the only place in our solar system where significant quantities of liquid are to be found (though most are liquid ethane and methane). That doesn’t seem to make much of a difference considering the chemistry of […]
Nature published these findings of scientists from Houston, Texas, about the original proportion of oxygen isotopes in the Sun. This problem is still not fully solved, and it has even split the science world into two groups, which published contradictory results from analyses of lunar soils, believed to contain embedded solar oxygen because the Moon […]
