Exoplanets

Because planets in other solar systems are extraordinarily difficult to see directly, astronomers have had to come up with innovative ways to hunt for them. Only recently have our technology and techniques been up to the task of finding exoplanets.

Solar System: Exploration

Humans have studied our solar system for thousands of years, but it was only in the last few centuries that scientists started to really figure out how things work. The era of robotic exploration—sending uncrewed spacecraft beyond Earth as our eyes and ears and senses—only started in the 1950s. A scientific fleet of robots is []

How Much Of The Solar System Have We Explored?

In this article, you will learn about how much of the solar system we have explored and what experts believe is out there. So, Estimates suggest that we have only explored around 5% of the universe, leaving the other 95% still to be discovered. This is an and

Physics professor explains exoplanets | Stanford Report

So, if we know that other solar systems formed with a similar history, then we could infer the planets that formed in those solar systems might have an Earth-like atmosphere.

18.1: Introduction to the Solar System

Since the early 1990s, astronomers have discovered other solar systems, with planets orbiting stars other than our own Sun (called "extrasolar planets" or simply "exoplanets") (Figure below). The extrasolar planet Fomalhaut is surrounded by a large disk of gas.

Searching for Other Solar Systems | D-Lab

Comparing to the Solar System Now let''s add the Solar System: Many of the multi-planet systems that we have discovered look pretty different to the Solar System! For example, all 7 of the TRAPPIST-1 planets orbit closer to their star than Mercury does to our

TESS discovers four exoplanets orbiting a nearby sun-like star

MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of

A New View of Exoplanets With NASA''s Upcoming Webb Telescope

According to Biller, "We could see years ago that for some of the planets we''ve already discovered, Webb would be really transformational." The James Webb Space Telescope will be the world''s premier space science observatory when it launches in 2021.

NASA And Google Just Announced They''ve Found Another Solar System

NASA and Google announced a "major discovery" on Thursday: another solar system with eight planets. That finding is due to the discovery of a new planet, Kepler-90i - a hot, rocky orb circling a sun-like star called Kepler-90, which is 2,545 light-years from Earth.

Did Kepler find a planet?

Kepler, a space telescope that trails Earth in orbit around the sun, has stared down 145,000 sun-like stars over the years to look for signs of distant planets. Astronomers knew about the Kepler-90 solar system, but had not previously detected this planet. It appears to be the third planet from the sun-like star, and orbits roughly every 14 days.
