**March 9th: The Day We Caught Our First Glimpse of the Infrared Universe**
Good evening, stargazers! On this date in 1983, humanity experienced what we might call a "cosmic awakening" when the Infrared Astronomical Satellite—or IRAS, as we affectionately call it—launched into orbit. And let me tell you, this little spacecraft absolutely changed *everything* we thought we knew about the universe.
Before IRAS, we were essentially looking at the cosmos with our eyes half-closed. Visible light? Sure, we had that down. But the infrared universe? That was completely hidden from us—like trying to understand a concert by only listening to a few select notes while the entire symphony plays in frequencies you can't hear.
When IRAS opened its infrared "eyes" to the heavens, it revealed an astonishing hidden cosmos. Dust clouds that were completely invisible suddenly blazed like beacons. Brand new stars being born in stellar nurseries lit up the night like celestial fireworks. And perhaps most dramatically, it discovered that many galaxies pour out MORE energy in infrared radiation than they do in visible light. Can you imagine? The universe was doing a cosmic light show we'd never even *seen* before!
This 60-centimeter telescope changed the trajectory of astronomy for decades to come, discovering things from asteroids to distant galaxies, all while gliding silently through the vacuum of space.
**So, stargazers, I encourage you to subscribe to the Astronomy Tonight podcast so you never miss these cosmic stories.** For more detailed information about tonight's sky or any astronomical events, be sure to check out **QuietPlease dot AI**.

President Barack Obama. Virginia, we are counting on you. Republicans want to steal enough seats in Congress to raid the next election and wield unchecked power for two more years. But you can stop them by voting yes by April 21st. Help put our elections back on a level playing field and let voters decide not politicians. Vote yes by April 21st. Paid for by Virginians for fair elections. Hi, I'm Alicia and I'm Stacy and we make trashy divorces. Everybody's favorite good podcast about bad relationships.

infrared universe. Good evening Star Grazers. On this date in 1983 humanity experienced what we might call a cosmic awakening when the infrared astronomical satellite or iras as we affectionately call it launched into orbit and look at this little spacecraft absolutely changed everything we thought we knew. Before iras we were essentially looking at the cosmos with our eyes half closed. Visible light sure we had that down but the infrared universe that was completely hidden from us like trying to understand the concept by only listening to a few select notes while the entire symphony plays in frequencies you can't hear. When iras opened its infrared eyes to the heavens it revealed an astonishing hidden cosmos. Dust clouds that were completely invisible suddenly blazed like beacons. Brand new stars being born in stellar nurseries lit up the night like celestial fireworks and perhaps most dramatically it discovered that many galaxies pour out more energy
in infrared radiation than they do invisible light. Can you imagine the universe was doing a cosmic light show we'd never even seen before. This 60 centimeter telescope changed the trajectory of astronomy for decades to come discovering things from asteroids to distant galaxies all while gliding silently through the vacuum of space. So stargazers I encourage you to subscribe to the astronomy tonight podcast so you never miss these cosmic stories.
