NASA chuẩn bị họp báo vào ngày 14/2: Đã tìm ra người ngoài hành tinh? by Kinh nghiá»‡m Tin há»�c

Những phát hiện của kính thiên văn Kepler sẽ được nói tới trong buổi họp báo này.

Theo Mirror, Cơ quan Hàng không Vũ trụ Hoa Kỳ (NASA) vừa thông báo sẽ tổ chức một buổi họp báo vào tối thứ Năm (ngày 14/12, giờ địa phương) sắp tới. Cuộc họp báo sẽ xoay quanh những phát hiện gần đây của kính viễn vọng Kepler mà nhiệm vụ của nó là đi tìm sự sống ngoài Trái Đất. Và cho tới thời điểm này, NASA vẫn đang giữ kín nội dung cụ thể của sự kiện.

Trong khi đó, thời gian gần đây, NASA đã làm việc với Google để khảo sát một số khu vực được gọi là "thế giới của người ngoài hành tinh". Cụ thể, NASA đã cung cấp nhiều dữ liệu quý giá cho Google từ các phát hiện của kính viễn vọng Kepler, để Google sử dụng máy học và trí thông minh nhân tạo (AI) để phân tích lượng dữ liệu này. Chính điều đó đã dấy lên nghi vấn: Có khi nào NASA sẽ tuyên bố đã tìm ra người ngoài hành tinh hay không?.

Kính thiên văn Kepler đã phát hiện ra hàng ngàn hành tinh bí ẩn ngoài hệ Mặt Trời.

Theo kế hoạch, buổi họp báo sắp tới của NASA còn có cả đại diện của Google, cụ thể là các nhà khoa học sau:

- Paul Hertz, Giám đốc bộ phận Vật lý thiên văn tại trụ sở NASA ở Washington.

- Christopher Shallue, kỹ sư phần mềm cấp cao của Google AI tại Mountain View, California.

- Andrew Vanderburg, nhà thiên văn học và là nghiên cứu sinh tại NASA Sagan (thuộc Đại học Texas).

- Jessie Dotson, nhà khoa học trong dự án Kepler tại Trung tâm nghiên cứu Ames của NASA.

Sau phần trình bày từ các nhà khoa học, giới truyền thông sẽ đặt ra nhiều câu hỏi để làm rõ hơn những tuyên bố mới từ NASA. Ngoài ra, các nhà khoa học cũng sẽ giải đáp những thắc mắc được gửi tới từ người dùng mạng xã hội Twitter khi họ đặt câu hỏi kèm #askNASA.

Kính thiên văn Kepler bắt đầu sứ mệnh của mình từ tháng 3/2009. Chính nó đã phát hiện ra tổng cộng 4.034 đối tượng nghi là hành tinh khác ngoài Trái Đất, trong đó có 2.335 đã được khẳng định là hành tinh. Đặc biệt, có 30 hành tinh trong số này có kích thước tương đương với Trái Đất, và đang quay quanh những ngôi sao. Thu nhỏ lại, NASA đang tập trung nghiên cứu 10 hành tinh có nhiều tiềm năng về sự sống.

Perseid Meteor Shower TONIGHT! by NASA's Marshall Space Flight Center

242 6

Thanks to a new moon, this week’s Perseid meteor shower is expected to be one of the best in years, and NASA Television will bring viewers a front row seat!

NASA’s Marshall Space Flight Center in Huntsville, Alabama, will broadcast a live program about this year’s Perseid meteor shower from 10 p.m. EDT Wednesday, Aug. 12 to 2 a.m. Thursday, Aug. 13. The event will highlight the science behind the Perseids, as well as NASA research related to meteors and comets. The program will air on NASA TV and NASA’s UStream channel.

The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Every August, the Earth passes through a cloud of the comet’s orbital debris. This debris field -- mostly created hundreds of years ago -- consists of bits of ice and dust shed from the comet which burn up in Earth’s atmosphere to create one of the premier meteor showers of the year.

The best opportunity to see the Perseid meteor shower is during the dark, pre-dawn hours of Aug. 13. The Perseids streak across the sky from many directions, with theoretical rates as high as 100 per hour. The last time the Perseids peak coincided with a new moon was in 2007, making this one of the best potential viewings in years.

Special guests on the live NASA TV broadcast include meteor experts Bill Cooke, Danielle Moser and Rhiannon Blaauw, all of NASA’s Meteoroid Environment Office, located at Marshall. They will provide on-air commentary, as well as answer questions online. Also scheduled to join the broadcast are experts from NASA’s Johnson Space Center in Houston, NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Ames Research Center in Moffett Field, California, the American Meteor Society and others.

Anyone can join in the conversation by tweeting questions to @NASA_Marshall with the hashtag #askNASA. Social media users may also post questions to Marshall’s Facebook page by replying to the Aug. 12 Perseid Q-and-A post.

Greenland ice sheet is changing by NASA Goddard Space Flight Center

123 3

At 1 p.m. EDT (10 a.m. PDT) on Friday, Aug. 28, NASA's Goddard Space Flight Center in Greenbelt, Maryland, will host a live TV program about agency research into how and why the massive Greenland ice sheet is changing. The event features scientists actively conducting field work in Greenland, along with extensive video footage of their work performed over this summer.

Panelists include: Tom Wagner (cryosphere program scientist with NASA's Earth Science Division), Laurence Smith (chair of the University of California, Los Angeles Department of Geography), Mike Bevis (professor of geodynamics at Ohio State University in Columbus), Sophie Nowicki (physical scientist at Goddard), and Josh Willis (JPL).

The Friday program will air live on NASA TV and stream online at: www.nasa.gov/nasatv. To ask questions via social media during the televised event, use the hashtag #askNASA.
