The full moon looms over the Washington Monument, while NASA’s Hubble reveals the Bubble Nebula, a 7-light-year structure formed by a massive star. This star emits gases at extreme temperatures, creating vibrant colors. Astronauts aboard the ISS experience the Panoramic View Effect, which reshapes their perception of Earth.
A bright full moon rises over the Washington Monument. The upper quarter of the monument, covered in scaffolding, is visible, its triangular tip seemingly pointing toward the pale moon above, which in this photo appears to be about twice as wide as the monument. The moon is shrouded in thin clouds, giving it a hazy appearance.
This elegant sphere, discovered by NASA’s Hubble TelescopeIt is known as the Bubble Nebula. Located 7,100 light-years from Earth, the Bubble Nebula has an impressive size of 7 light-years. The boiling star that forms this nebula is 45 times more massive than our Sun!
The star’s gas heats up so much that it escapes into space in the form of a stellar wind moving at more than four million miles per hour (6.4 million kilometers per hour). The gases, heated to different temperatures, emit different colors: blue for oxygen, green for hydrogen and red for nitrogen.
The Bubble Nebula formed about four million years ago, and within 10 to 20 million years, the star at its core will likely detonate as a supernova.
“This is so cute,” one user commented on NASA’s post, while another wondered how gas in space can transform into colors.
The waxing gibbous Moon is photographed from the International Space Station as it orbits 265 miles above the U.S. state of Minnesota on December 17, 2021.
Observing Land The fact that people are in space can alter an astronaut’s cosmic perspective, a mental shift known as the “overview effect.” The term, first coined by space writer Frank White in 1987, describes a feeling of wonder about our home planet and a sense of responsibility to care for it.
The Overview Effect can create major changes in the way you think about Earth and life. Astronauts often use the words “beautiful” and “fragile” to describe the experience. As the International Space Station soared 262 miles (422 kilometers) above Western Australia, NASA astronaut Jeanette Epps captured this long-duration photograph, or an image captured by a camera set to a slower shutter speed.
This image was liked by more than 755,100 people, who commented: “The Earth acquired a green aura.”
POT The Hubble telescope captured this image of the Red Spider Nebula, a planetary nebula 3,000 light-years from Earth. It is located in the constellation Sagittarius.
The Red Spider Nebula is home to one of the hottest stars known, which heats the surrounding gas and forms shock waves 100 billion kilometres high. These waves form the spider-like arcs seen in this image, with the star at the centre resembling a black widow’s hourglass.
