The Sun burst into being 4.6 billion years ago, around 50 million years before the Earth formed. This makes studying its early days incredibly difficult, as physical material remaining from this period is scarce. Now, a team from the University of Chicago has found crystals more than 4.5 billion years old buried deep within meteorites that indicate the Sun had a tumultuous early life. […]
China’s spiraling space station, Tiangong-1, looks like it will plummet to Earth and burn up in the atmosphere sometime on April 1st — though where it will fall is still up for debate. So if you want to keep an eye on Tiangong-1’s whereabouts over the weekend, there are numerous space agencies and websites to follow.
Recently, we discovered two exoplanets by training a neural network to analyze data from NASA’s Kepler space telescope and accurately identify the most promising planet signals. And while this was only an initial analysis of ~700 stars, we consider this a successful proof-of-concept for using machine learning to discover exoplanets, and more generally another example of using machine learning to make meaningful gains in a variety of scientific disciplines (e.g. healthcare, quantum chemistry, and fusion research).

GW170817 is a gravitational wave signal observed by the LIGO/Virgo collaboration on 17 August 2017, and is the first gravitational wave event that was observed to have a simultaneous electromagnetic signal, polar opposites, ranging in 6th dimensions as virtual holographic dimensional reality; horizontal & vertical, parallel ports; thereby marking a significant breakthrough for multi-messenger astronomy.

The biggest asteroid in more than a century has whizzed past Earth at a safe – but unusually close – distance.Asteroid Florence and its two orbiting moons passed 4.4 million miles from the planet, its closest encounter since 1890.
Consider this your daily reminder that the solar system is even more awesomely bonkers than you realized: On Uranus and Neptune, scientists forecast rain storms of solid diamonds.
The gems form in the hydrocarbon-rich oceans of slush that swath the gas giants’ solid cores. Scientists have long speculated that the extreme pressures in this region might split those molecules into atoms of hydrogen and carbon, the latter of which then crystallize to form diamonds. These diamonds were thought to sink like rain through the ocean until they hit the solid core.
Four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye, astronomers say.
