00:00Kuya Chris, we have a question of the day from Scarlett Avery Peñalosa, 8 years old from Las Pinas City.

00:06She's from the country.

00:08She asked, if a person hasn't been to the end of the galaxy,

00:12let's admit that he has seen and studied it.

00:16Good question.

00:17Good question.

00:19You know, a lot of people are posting pictures of other planets and our galaxy.

00:25Is that true?

00:26Or is it just done by AI or artificial intelligence?

00:29Yes, that's still popular.

00:31AI is really good.

00:32Maybe some are made by AI.

00:34But it's true that stars and galaxies are taken by pictures and videos

00:39that are very far from the help of advanced technology.

00:44Do you know the technology that I'm talking about?

00:48Isn't it curious?

00:49What is it, Kuya Chris?

00:50Because it can.

00:51It can really be taken.

00:53So to see is to believe.

00:54Guys, let's watch this.

00:56This is good.

00:58The most distant picture of space is from the Hubble Telescope,

01:01named after the American astronomer Edwin Hubble,

01:05who said that the cosmos is full of other galaxies.

01:09Hubble died in 1953 before his theory was proven.

01:14But in 1990, the telescope named after him was sent to the Discovery Shuttle to space.

01:22The pictures sent by the telescope gave way to scientists

01:26to confirm Hubble's theory by revealing thousands of galaxies

01:31that are 13.2 billion light-years away.

01:34Wow! Out of this world!

01:36Hubble is responsible for most of what we know about deep space.

01:41It confirmed Edwin Hubble's theory that the universe has many dimensions and expansions.

01:47It helped Big Bang to return to 13.7 billion years ago.

01:53It showed the huge black hole in the middle of the universe.

01:57And it became important in finding extrasolar planets.

02:01It's trivia time!

02:03How long did Hubble take to travel around the Earth?

02:08A. 95 minutes

02:10B. 95 hours

02:12or C. 95 days

02:14The answer is A. 95 minutes.

02:17A telescope can zoom while traveling at 17,000 miles per hour.

02:23And it can also capture an insect from a distance of 7,000 miles.

02:28In 2021, James Webb Space Telescope was launched,

02:32the $9 billion billionaire of Hubble.

02:36This level-up deep space telescope will travel 1,000 miles in space

02:42compared to the 350 miles of Hubble.

02:46Only time will tell what new discoveries are waiting for us at the end of space.
