👉Voyager 1 is still sending information back to Earth from interstellar space, now roughly 15.8 billion miles away. At that enormous distance, even signals traveling at the speed of light need over 22 hours to reach us. The spacecraft passed the heliopause in 2012, crossing the boundary where the Sun’s solar wind fades and the vast region between stars begins. This area, called the interstellar medium, contains thin gas, dust, and high-energy radiation. This achievement is important because Voy

Amazing INTERSTELLAR ! what is INTERSTELLAR ? What is INTERSTELLAR medium? Who is travelling there? All details are in this video. >You never seen it before. Really Awesome. Our Milky Way galaxy is home to more than 100 billion stars that are often separated by trillions of miles. The spaces in between, called the interstellar medium, aren't empty –– they're sprinkled with gas and dust that are both the seeds of new stars and the leftover crumbs from stars long dead.

Our Interstellar Medium | NASA Goddard FriendsofNASA.org: Our Milky Way galaxy is home to more than 100 billion stars that are often separated by trillions of miles. The spaces in between, called the interstellar medium, are not empty—they are sprinkled with gas and dust that are both the seeds of new stars and the leftover crumbs from stars long dead. Studying the interstellar medium with observatories like NASA’s upcoming Nancy Grace Roman Space Telescope will reveal new insight into the galac
