With the help of citizen scientists, astronomers have discovered two highly unusual brown dwarfs, balls of gas that are not massive enough to power themselves the way stars do.
Participants in the NASA-funded Backyard Worlds: Planet 9 project helped lead scientists to these bizarre objects, using data from NASA’s Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) satellite along with all-sky observations collected between 2009 and 2011 under its previous moniker, WISE. Backyard Worlds: Planet 9 is an example of “citizen science,” a collaboration between professional scientists and members of the public.
Scientists call the newly discovered objects “the first extreme T-type subdwarfs.” They weigh about 75 times the mass of Jupiter and clock in at roughly 10 billion years old. These two objects are the most planetlike brown dwarfs yet seen among the Milky Way’s oldest population of stars.

*** NOTE: Press release are usually published under that page “Media Releases (Information for Journalist).” These press releases are usually meetings or presentation of studies. The public will most of the time have access to view or listen to most of these, but only credentialed media can ask question.
Also, before the meeting documentation may be made available, sometimes weeks before the meeting. If the documents are embargoed, we in the press know that means the information cannot be published before the embargo date and time. We use the time to pre-write our stories and prepare questions, but the embargo must be honored by all.

Want to become an astronaut to visit Mars?
Today, NASA put out a press release with information on how to apply to become an astronaut for the future manned flight to Mars.
Normally these just go into the page for Media Releases. But this is a good time to tell you that I have created a new page called:
below is the beginning of the press release. The link after it takes you to our new Media page.
While many options such as asking questions and getting access to their teleconference systems, with most press releases, if a meeting or a panel is conviened, NASA will allow the public to view it live either on its website or on NASA TV.
Each press release has all the information you need to watch and listen to the questions the press ask and the respones they get.
The link to the new page is: Media Releases (Information For Journalists)
This page is also available and lists below it with “–” showing the releases available. Click on the 3 lines in the upper right corner to see all the pages we have and to access all the press releases we get.
Here is the first two paragraph of the press release asking for applications to anyone who thinks they can become an astronaut. Good luck to anyone applying.
“In anticipation of returning human spaceflight launches to American soil, and in preparation for the agency’s journey to Mars, NASA announced it will soon begin accepting applications for the next class of astronaut candidates. With more human spacecraft in development in the United States today than at any other time in history, future astronauts will launch once again from the Space Coast of Florida on American-made commercial spacecraft, and carry out deep-space exploration missions that will advance a future human mission to Mars.
The agency will accept applications from Dec. 14 through mid-February and expects to announce candidates selected in mid-2017. Applications for consideration as a NASA Astronaut will be accepted at…”
