This isn't an expanding star: this is a light echo!
In this time-lapse sonification, a pulse of light from the star V838 Monocerotis gives the illusion that the surrounding dust is expanding. In reality, it's just the light from the star's flash reaching dust farther away.
#Hubble
Hubble captured the first image #OTD in 2002!
This star is 20,000 light-years away, at the outer edge of our Milky Way Galaxy. In this sonification, scientists mapped brightness to pitch and volume, and the surrounding stars are pitched to musical notes: go.nasa.gov/3WescRA

America's first spacecraft to orbit Venus, the Pioneer-Venus Orbiter, was launched #OTD in 1978. The spacecraft's radar penetrated Venus's thick atmosphere, allowing scientists to produce this topographical map of the surface. @NASASolarSystem

Climate change is causing rising sea levels, longer and more intense heat waves, melting ice, extreme weather events and more.
But there are other, often surprising, ways Earth’s changing climate is affecting our world. 🧵 go.nasa.gov/3pNh4Pg

A new NASA Climate feature series examines some of the lesser-known, and often surprising, ways global climate change is affecting our world. First up: transportation.Climate Change: Vital Signs of the Planet
Climate change may make airline flights bumpier. 🛩️
Climate change may strengthen vertical wind shear in jet streams – creating irregular air motions, or turbulence. Pilots use or avoid jet streams to make flights more efficient.
#NASAEarth
As Arctic sea ice melts due to climate change, sailing through the Arctic Ocean could become easier and shorten travel times.
However, traveling over sea ice using snowmobiles, trucks or other vehicles could become unsafe as the ice thins. 🧊
#NASAEarth
Climate change is expected to increase the frequency and intensity of droughts and floods.
Water levels in rivers and reservoirs could shift drastically, impacting cargo ships. 🚢 go.nasa.gov/3pNh4Pg
