The strange orbit of a distant object is likely due to a massive, undiscovered ninth planet traveling deep beyond Neptune, according to new models.

A little-known feature in Google Maps lets you explore our local solar system — here’s how to visit Mercury, Venus, and other planets and moons in Google Maps
Most people just use Google Maps to get directions from A to B, but it’s also an incredible educational tool in its own right.
Using Google Maps is a great way to learn more about the various cities and countries around the world. But many people might not know that Google Maps can also be used to explore other worlds besides Earth.
That’s right: If you visit Google Maps and zoom out far enough, you’ll have the option to explore several planets and moons in our own solar system.
How NASA Will Unlock the Secrets of Quantum Mechanics Aboard the ISS
An Antares rocket launched from Virginia before sunrise this morning and is on its way to the International Space Station. Its 7,400 pounds of cargo include an experiment that will chill atoms to just about absolute zero—colder than the vacuum of space itself.
The Cold Atom Laboratory (CAL) is set to create Bose-Einstein condensates on board the ISS. But what’s a Bose-Einstein condensate? And why make it in space?
“Essentially, it’s going to allow us to do different kinds of things than we’d be able to do on Earth,” Gretchen Campbell, co-director of the University of Maryland’s Joint Quantum Institute, told Gizmodo.
Hubble reveals the local universe in glorious ultraviolet detail
An international team of astronomers has completed the most comprehensive ultraviolet survey of the local universe to date, with the help of the venerated Hubble Space Telescope. The newly-released survey data will help scientists to better understand how stars come to form, and the processes by which galaxies like our own Milky Way evolve over time.
A Newly Discovered Solar System Object Hints at Hidden Planet Nine

There might be a large planet lurking somewhere at the very edge of our solar system, and astronomers are hunting for it. While they have yet to find direct evidence of the planet, a recent discovery provides yet more indirect evidence that the planet does, in fact, exist. Astronomers found a small solar system body with a strange orbit that they say can only be explained by another, bigger planet hiding out there somewhere.
Can we get 100 percent of our energy from renewable sources?
Is there enough space for all the wind turbines and solar panels to provide all our energy needs? What happens when the sun doesn’t shine and the wind doesn’t blow? Won’t renewables destabilise the grid and cause blackouts?
In a review paper last year in the high-ranking journal Renewable and Sustainable Energy Reviews, researcher Benjamin Heard and colleagues presented their case against 100 percent renewable electrical systems. They doubted the feasibility of many of the recent scenarios for high shares of renewable energy, questioning everything from whether renewables-based systems can survive extreme weather events with low sun and low wind, to the ability to keep the grid stable with so much variable generation.
Now, scientists have hit back with their response to the points raised by Heard and colleagues. The researchers from the Karlsruhe Institute of Technology and collaborators have analysed hundreds of studies to answer each of the apparent issues. They demonstrate that there are no roadblocks to a 100 percent renewable future.

Astronomers release most complete ultraviolet-light survey of nearby galaxies
Capitalizing on the unparalleled sharpness and spectral range of NASA’s Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.
The researchers combined new Hubble observations with archival Hubble images for 50 star-forming spiral and dwarf galaxies in the local universe, offering a large and extensive resource for understanding the complexities of star formation and galaxy evolution. The project, called the Legacy ExtraGalactic UV Survey (LEGUS), has amassed star catalogs for each of the LEGUS galaxies and cluster catalogs for 30 of the galaxies, as well as images of the galaxies themselves. The data provide detailed information on young, massive stars and star clusters, and how their environment affects their development.
“There has never before been a star cluster and a stellar catalog that included observations in ultraviolet light,” explained survey leader Daniela Calzetti of the University of Massachusetts, Amherst. “Ultraviolet light is a major tracer of the youngest and hottest star populations, which astronomers need to derive the ages of stars and get a complete stellar history. The synergy of the two catalogs combined offers an unprecedented potential for understanding star formation.”
