This week on Space Curious, a listener wanted to know, "How big is the solar system?"

(AP Photo/Kin Cheung)NEW DELHI – India reported another 86,052 coronavirus cases in the past 24 hours, a declining trend with recoveries exceeding new cases this week. India's newly reported infections have remained below 90,000 for five straight days after hitting a record 97,894 on Sept. 16. The total number of tests have crossed 67 million so far in the country with nearly 1.4 billion people. Antigen tests look for virus proteins while RT-PCR tests look for genetic material from the virus. Hong Kong reported seven new cases on Friday for a total of 5,056, including 104 deaths, according to China’s National Health Commission.

NEW YORK The Magic School Bus has traveled everywhere from Pluto to inside the human body. Scholastic Entertainment said Thursday that it will make a feature-length, live-action hybrid film based on the animated TV show that ran from 1994 to 1997. Elizabeth Banks will play the manic science teacher Ms. Frizzle. The Magic School Bus, adapted from a series of books written by Joanna Cole and illustrated by Bruce Degen, centers on a group of school children who board a yellow school bus for field trips to such unlikely places as outer space or the human digestive system. Lilly Tomlin supplied the voice for Ms. Frizzle in the original cartoon series and Kate McKinnon voiced her sister in a recent Netflix reboot, The Magic School Bus Rides Again.The film version will be led by Scholastic Entertainment, Brownstone Productions, Marc Platt Productions and Universal Pictures.

This heat could have been enough to melt ice and form a subsurface ocean. Now, using geologic observations of Pluto's surface, new research suggests that Pluto actually started out in a hot formation scenario. Researchers modeled and compared hot versus cold formation scenarios and found that the surface features on Pluto best match hot. "As Pluto was forming, material was repeatedly coming in and impacting the surface," Bierson said. We calculate that Pluto would have had to form in less than about 30,000 years for this to form an ocean."

(CNN) -- From its unique vantage point 4.3 billion miles from Earth, NASA’s New Horizons spacecraft has captured images of nearby stars — and the stars appear to be in different positions than where we see them from Earth. In April, at a distance of 4.3 billion miles from Earth, New Horizons aimed its long-range telescopic camera to nearby stars Proxima Centauri and Wolf 359. However, the images captured by New Horizons could be compared to images taken on the same days by Earth-based telescopes, which made the shift obvious. The New Horizons image of star Wolf 359 is on the left. "The New Horizons spacecraft continues to speed away from Earth toward interstellar space and is continuing to return exciting new data for planetary science."
