Summary:

• **Hidden Galaxies in Space**: Scientists discovered that some galaxies we thought were "dead" and stopped making new stars might actually still be alive and creating stars, but we just can't see them because thick clouds of dust are hiding the starlight. It's like looking for a flashlight in a dark room covered with blankets!

• **New Ways to Find Secret Galaxies**: Astronomers are using special telescopes that can see through dust, like infrared cameras that detect heat instead of visible light, to find these hidden galaxies and understand how many stars are really being born in the universe. This helps us get a better picture of how galaxies grow and change over billions of years.
