Or maybe even something smaller: Unlike any other exoplanet-hunting telescope, the Roman will be able to detect planets as small as a few times the mass of the moon.
Astronomers don’t know if our solar system, dominated by Jupiter and Saturn, is typical, or if ice giants like Neptune and Uranus are more common. We will, as necessary, adjust from the traditional first Tuesday at 8 PM schedule to accommodate our. As usual, the recording will also be posted on our YouTube channel. This lecture will be presented with a livestream to YouTube, and questions can be asked in the YouTube chat.
ROMAN SPACE TELESCOPE. SERIES
Instead, it will focus on planets orbiting far away from their suns, analogous to the gas and ice giants of our solar system. The 2023 Public Lecture Series is continuing an online-only format.
Since the microlensing technique has trouble identifying planets orbiting close to their parent stars, the Roman Space Telescope won’t be able to pick out an Earth 2.0, though. That will give astronomers critical information as to how chaotic solar system formation is, which will help fine-tune models of the development of Earth-like planets. That will allow it to make the first wide-field infrared. The Roman can find wandering exoplanets as small as Mars, and could potentially expand our catalog to a few hundred. During its first five years, Roman will image more than 50 times as much sky as the Hubble Space Telescope covered in its first 30 years. Astronomers know of only a couple dozen of these lost souls, but they estimate that our galaxy could be swarming with hundreds of billions of them.
The interloping object could be an entire planetary system, or it could be a wandering, “rogue” exoplanet, detached from any star.
