This is probably one of the coolest images I’ve ever processed! This is Jupiter’s moon, Europa. As the Juno spacecraft orbits Jupiter, it can sometimes point its camera away from the planet itself. Here’s the catch, Jupiter is millions of miles from Earth and it takes power to transmit data. Therefore, Juno transmits barebones images and data. It’s up to us here on Earth to use computers to piece the data together and process the images. #nasa #juno #jupiter #space #solarsystemambassador #europa https://www.instagram.com/p/CdUh1l-OTAH/?igshid=NGJjMDIxMWI=

An American Heritage Girls troop invited me to come speak about astronomy and women in STEM / Space Science. The girls had amazing questions and I got to be dramatic in my teaching. #astronomy #nasa #stem #stemgirls #solarsytemambassador #americanheritagegirls https://www.instagram.com/p/CZN4_eHsAjJ/?utm_medium=tumblr

NASA Astronauts Robert Behnken and Douglas Hurley undock from the International Space Station at 7:34 p.m. EDT tonight, bringing to a close their ~2 month Launch America mission. Check out these science highlights from the 100+ hours of work they completed aboard the orbital lab.

Hosted a “Story Time From Space” event today at Kate’s camp. The kids learned about the ISS and all of the exciting experiments taking place up there. They also made artwork for the Space for Art Foundation’s BEYOND project. @issnationallab @spaceforartfoundation @iss #iss #space #issnationallab #astronauts #spacestation #science #stem @nasa #nasa https://www.instagram.com/p/CDCKwFKnIG3/?igshid=116ibjl2qrlwa

Hubble Peers at Cosmic Blue Bauble

NASA - Hubble Space Telescope patch. April 12, 2019

Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all. Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered. However, what makes Messier 3 extra special is its unusually large population of variable stars — stars that fluctuate in brightness over time. New variable stars continue to be discovered in this sparkling stellar nest to this day, but so far we know of 274, the highest number found in any globular cluster by far. At least 170 of these are of a special variety called RR Lyrae variables, which pulse with a period directly related to their intrinsic brightness. If astronomers know how bright a star truly is based on its mass and classification, and they know how bright it appears to be from our viewpoint here on Earth, they can thus work out its distance from us. For this reason, RR Lyrae stars are known as standard candles — objects of known luminosity whose distance and position can be used to help us understand more about vast celestial distances and the scale of the cosmos. Messier 3 also contains a relatively high number of so-called blue stragglers, which are shown quite clearly in this Hubble image. These are blue main sequence stars that appear to be young because they are bluer and more luminous than other stars in the cluster. As all stars in globular clusters are believed to have formed together and thus to be roughly the same age, only a difference in mass can give these stars a different color. A red, old star can appear bluer when it acquires more mass, for instance by stripping it from a nearby star. The extra mass changes it into a bluer star, which makes us think it is younger than it really is. Messier 3 is featured in Hubble’s Messier catalog, which includes some of the most fascinating objects that can be observed from Earth’s Northern Hemisphere.

Due to differences in pressure, temperature, and composition of atmospheres, sound waves would travel differently to our ears on Mars. This video shows how I sound on Earth and how I would sound on Mars. (turn sound on) #SolarSystemAmbassador #space #mars #perseverance https://www.instagram.com/p/CMSX5DDD_Dm/?igshid=1wa38o2h8446q
