Come check out NASA Langley's coolest wind tunnel yet: the National Transonic Facility (NTF)! The NTF is the world's largest pressurized cryogenic wind tunnel. Chill out with the NTF at our open house on Saturday, Oct. 21: openhouse.larc.nasa.gov #NASALangleyOH

Building 1236: The National Transonic Facility

The NTF is the world's largest pressurized cryogenic wind tunnel.

Electrons’ movements in atoms and molecules are so rapid that they are measured in attoseconds. An attosecond is to one second as one second is to the age of the universe. #NobelPrize

While studying the exoplanet K2-18 b, @NASAWebb hinted at a detection of dimethyl sulphide (DMS). On Earth, this molecule is only produced by microbial life. Because the detection needs to be confirmed, the team will follow up with additional observations. go.nasa.gov/3Ll92VL
A graphic titled “Exoplanet K2-18 b: Atmosphere Composition.” The graphic shows the spectra of the exoplanet K2-18 b from NIRISS and NIRSpec in the form of a graph, with the vertical y-axis labeled as Amount of Light Blocked and the horizontal axis labeled as Wavelength of Light (microns). The data is plotted as dots with vertical error bars. A jagged blue line running through the plot represents the best-fit model. There are semi-transparent magenta, red and green vertical columns also scattered across the plot, indicating where variations in the line represent the presence of methane, carbon dioxide, and dimethyl sulfide (combined with other molecules), respectively. Behind the graph is an illustration of the planet and star. The planet is a large fuzzy blue-ish sphere off to the right, taking up half of the background. The red star is smaller at the bottom left of the entire graphic.

Picoflare jets power the solar wind from a coronal hole on the Sun. The jets reach speeds of 100 km/s and can play a role in the generation of shear instabilities, producing structures in the solar wind. science.org/doi/10.1126/scie…

Picoflare jets power the solar wind emerging from a coronal hole on the Sun

Extreme ultraviolet images of the Sun show numerous small-scale jets that could supply plasma to the solar wind.

Large water sphere in 0g. This sphere is the size of my head and when hit with a puff of air, shows surprising dynamics due to the diminishing role of surface tension as diameter increases. Video 3X slower from Exp 30 in 2012
