An artist's depiction of the planet TOI 700 d.

The universe has always been mysterious to people, and scientists from all over the world are studying it. Three days ago, a piece of shocking news nearly hogged all the headlines of the newspaper–an earth-sized planet has been found! What will that planet look like? Are there any lives on the planet? Let’s listen to the audio to learn more.

When scientists search for alien planets, they get a special thrill when they find one that seems to reflect our own world back to us. A NASA satellite has discovered an Earth-sized planet within its star’s “habitable” area — where liquid water could possibly exist., and it is called ‘TOI 700D’.

The star’s world is known as an exoplanet. This term is used for planets that orbit a star outside of our own __________(2 words missing). Unlike its neighbors — and the vast majority of planets scientists have identified so far — it seems to be about the same size as Earth and to orbit its star at a distance that would allow water to remain liquid on its surface.

The finding of the TOI 700D is of a great ___________(1 word missing) to scientists. It helps us to explore whether life can form on the planets around very small stars. But despite the excitement, the scientists involved in the discovery don’t know much about the TOI 700 d. First, they know that its star, a red dwarf, looks more pleasant than some dwarfs. Active stars can blast radiation and highly charged matter from planets orbiting them, potentially annihilating those worlds.

“It’s absolutely quiet,” Emily Gilbert, a graduate student in astronomy at the University of Chicago, “We have 11 TESS data, but I don’t see a single flare. The star is a little older, so we hope it will calm down during its lifetime.”

The scientists have spotted three planets so far around this quiet star: TOI 700 b, c and d. The first two orbit too close to the star to be promising worlds for life, but the third orbits in the magic ring scientists call _______________(3 words missing), where temperatures allow water to remain liquid on a planet’s surface. “It’s actually farther into the habitable zone than Earth; Earth itself is barely habitable,” Gilbert said.

They are also confident, although not positive, that this planet is tidally locked — the same side always faces its star in a constant day, while the other side is in constant night.

But from there, uncertainty began to pile up. In particular, scientists studying TOI 700 d wanted a key measure: it’s mass. Therefore, It remains to be seen whether life can survive there.

That’s all for [Listening] today!
