A small, recently discovered asteroid -- or perhaps a comet -- appears to have originated from outside the solar system, coming from somewhere else in our galaxy. If so, it would be the first "interstellar object" to be observed and confirmed by astronomers.
This unusual object – for now designated A/2017 U1 – is less than a quarter-mile (400 meters) in diameter and is moving remarkably fast. Astronomers are urgently working to point telescopes around the world and in space at this notable object. Once these data are obtained and analyzed, astronomers may know more about the origin and possibly composition of the object.
A/2017 U1 was discovered Oct. 19 by the University of Hawaii's Pan-STARRS 1 telescope on Haleakala, Hawaii, during the course of its nightly search for near-Earth ob
NASA will discuss new results about ocean worlds in our solar system from the agency’s Cassini spacecraft and the Hubble Space Telescope during a news briefing 2 p.m. EDT on Thursday, April 13. The event, to be held at the James Webb Auditorium at NASA Headquarters in Washington, will include remote participation from experts across the country.
The briefing will be broadcast live on NASA Television and the agency's website.
These new discoveries will help inform future ocean world exploration -- including NASA’s upcoming Europa Clipper mission planned for launch in the 2020s -- and the broader search for life beyond Earth.
The news briefing participants will be:

NASA's Cassini spacecraft, in orbit around Saturn since 2004, is about to begin the final chapter of its remarkable story. On Wednesday, April 26, the spacecraft will make the first in a series of dives through the 1,500-mile-wide (2,400-kilometer) gap between Saturn and its rings as part of the mission’s grand finale.
"No spacecraft has ever gone through the unique region that we'll attempt to boldly cross 22 times," said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "What we learn from Cassini’s daring final orbits will further our understanding of how giant planets, and planetary systems everywhere, form and evolve. This is truly discovery in action to the very end."
During its time at Saturn, Cassini has made num
President Trump has signed the NASA Transition Authorization Act of 2017.
For the first time in nearly seven years, the U.S. government has passed a new long-term vision for NASA's future.
The new law calls to give NASA a $19.5 billion budget and asks NASA to reach Mars by 2033. However, the law leaves out earth science, which the Trump administration intends to cut heavily.
President Donald Trump signed the NASA Transition Authorization Act of 2017, a bill also known as S.442, into law in the Oval Office on March 21. The Senate and House had collaborated on the document for months, and it requests a $19.5 billion-a-year budget for the space agency. (NASA received $19.3 billion in 2016, or 0.5 percent of the total federal budget.)
In an image that Trump tweeted on Tuesday, the pres...
Moon Express announced Jan. 13 that it has closed a $20 million financing round, giving the company sufficient funds for an attempt to win the Google Lunar X Prize later this year.
The new investment, which the company calls a Series B-1 round, comes from a mix of new and existing investors. The company’s investors include venture capital firms Founders Fund and Social Capital, as well as software company Autodesk. Several individual investors also participated in the latest round.
Moon Express Chief Executive Bob Richards said one of the company’s co-founders, billionaire Naveen Jain, played a key role in the round. “He not only participated at a significant financial level, but also gave other investors the confidence through his commitment that they should invest as well,” Richa
