Article of the Week for November 16, 215 Venus’ Twin? New Earth-Sized Exoplanet GJ1132b Found in Our Neighborhood (1060L) Due Friday, November 20, 2015 Instructions: COMPLETE ALL QUESTIONS AND MARGIN NOTES using the CLOSE reading strategies practiced in class. This requires reading of the article three times. Step 1: Skim the article using these symbols as you read: (+) agree, (-) disagree, (*) important, (!) surprising, (?) wondering Step 2: Number the paragraphs. Read the article carefully and make notes in the margin. Make a note for EVERY paragraph Notes should include: o Comments that show that you understand the article. (A summary or statement of the main idea of important sections may serve this purpose.) o Questions you have that show what you are wondering about as you read. o Notes that differentiate between fact and opinion. o Observations about how the writer’s strategies (organization, word choice, perspective, support) and choices affect the article. Step 3: A final quick read noting anything you may have missed during the first two reads. Your margin notes are part of your score for this assessment. Answer the questions carefully in complete sentences unless otherwise instructed. Name ________________________________________________________ AM MID PM Venus' Twin? New Earth-Sized Exoplanet GJ 1132b Found in Our Neighborhood Notes on my thoughts, reactions and questions as I read: There's a new rocky Earth-size exoplanet on our galactic block, and it's a sizzler. Astrophysicists on Wednesday revealed the newfound world, GJ 1132b, named after the small nearby star that it orbits. Even though the mercury can hit 450 degrees at this planet, it's cool enough to have a thick Venus-like atmosphere. Lucky for scientists, it's close enough to find out. Planet GJ 1132b is just 39 light-years away, within the atmospheric study range of the Hubble Space Telescope. Given that a single light-year represents 5.87 trillion miles — the distance light can travel in a year — this planet is about 230 trillion miles away. A team led by Massachusetts Institute of Technology's Zachory Berta-Thompson discovered the planet in May, using telescopes in AP. Venus’ twin?

Notes on my thoughts, reactions and questions as I read: While the scientists say the planet is too hot for life, it's still much cooler than the rocky fireballs known to orbit stars beyond our solar system. The official term for a planet outside our solar system is exoplanet. "If we find this pretty hot planet has managed to hang onto its atmosphere over the billions of years it's been around, that bodes well for the long-term goal of studying cooler planets that could have life," Berta-Thompson said in a statement. Berta-Thompson and the others estimate that GJ 1132b has a diameter of about 9,200 miles, slightly bigger than Earth. Its mass, however, is thought to be 60 percent greater than Earth's. Its home star — GJ 1132 — is a red dwarf one-fifth the size of our sun. The planet circles every 1.6 days from just 1.4 million miles out, thus the heat wave. A slight dip in the starlight every 1.6 days was the giveaway for the observing team. "Our ultimate goal is to find a twin Earth," said astronomer David Charbonneau of the Harvard-Smithsonian Center for Astrophysics, one of the authors, "but along the way we've found a twin Venus." He added in a statement: "We suspect it will have a Venus-like atmosphere, too, and if it does, we can't wait to get a whiff." The astronomers are seeking follow-up observations from Hubble and the Spitzer Space Telescope. The James Webb Space Telescope, due to launch in 2018, and other future craft could provide even more details. In a companion article in Nature, the University of Maryland's Drake Deming points out astronomers will be able to study GJ 1132b with "unprecedented fidelity" given its proximity and also the small size of its star, which should minimize light interference with the measurements. That, in large part, makes it in his words "arguably the most important planet ever found outside the solar system." He was not involved with the study. It's unknown, for now, whether this star system harbors other planets. Scan QR code to access the video link. AP. Venus’ twin? New Earth-sized exoplanet GJ1132b found in our neighborhood. NBC News.
