Doomed Star Eta Carinae

Eta Carinae may be about to explode. But no one knows when – it may be next year, it may be one million years from now. Eta Carinae’s mass – about 100 times greater than our Sun – makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural LASER light.

This featured image brings out details in the unusual nebula that surrounds this rogue star. Diffraction spikes, caused by the telescope, are visible as bright multi-colored streaks emanating from Eta Carinae’s center. Two distinct lobes of the Homunculus Nebula encompass the hot central region, while some strange radial streaks are visible in red extending toward the image right. The lobes are filled with lanes of gas and dust which absorb the blue and ultraviolet light emitted near the center. The streaks, however, remain unexplained.

NASA to Provide Crew Flight Test, Space Station Missions Update

NASA will host a media teleconference at 12:30 p.m. EDT, Wednesday, Aug. 7, to discuss ongoing International Space Station operations, including the agency’s Boeing Crew Flight Test and NASA’s SpaceX Crew-9 mission.  

Audio of the briefing will stream live on NASA’s website.

Agency participants include:

• Ken Bowersox, associate administrator, Space Operations Mission Directorate
• Steve Stich, manager, Commercial Crew Program
• Dana Weigel, manager, International Space Station Program

To ask questions during the teleconference, media must RSVP no later than two hours prior to the start of the call to Jimi Russell at: james.j.russell@nasa.gov. NASA’s media accreditation policy is available online.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge, demonstrating new technologies, and making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.
