Exoplanets are planets that lie outside of our solar system, and researchers can use telescopes to study their atmospheres.
But until the launch of NASA’s JWST, the largest optical telescope in space, researchers haven’t been able to determine whether rocky exoplanets—planets composed mostly of rocks rather than gas giants such as Jupiter and Saturn—are able to build and maintain atmospheres.

To illustrate how hard it is to launch a spacecraft, we can use familiar vehicles as examples. A standard car burns about 13 gallons (50 liters) of gasoline to travel about 370 miles (600 kilometers) at a maximum speed of 74 miles (120 kilometers) per hour.
To launch a spacecraft beyond the Earth's atmosphere , we have to use the parabolic trajectory we learned about in school. But once it reaches the peak of the parabola, we have to make sure it doesn't start falling back to Earth.
Sky This Month: May 2023 | Astronomy.com
Venus puts on its best show of the year in the evening sky, visible until very late. Mars also continues as an evening object, while other planets congregate in the morning.
We start the monthly tour with Venus shining brilliantly in the western sky. It glows at magnitude –4.1 at the start of the month and brightens by three-tenths of a magnitude by May 31. You'll find it nicely placed between the horns of Taurus the Bull on the 1st.
