While researching a topic, student has taken the following notes: Astronomer Matthew Kenworthy was searching for rings around exoplanets when he noticed the sunlike star, ASASSN-21qj dimming repeatedly.Infrared data from the WISE telescope showed that the star had increased infrared radiation about 900 days before the dimming started.Researchers suggest the infrared glow was caused by two planets colliding and forming a new body of rock.Their calculations also suggest that the dimming Kenworthy noticed was caused by impact debris blocking the rock’s light.If their conclusions are correct, astronomers may be able to observe what happens after a planetary collision and possibly even the formation of a new planet. The student wants to emphasize what researchers think accounts for the strange phenomenon observed around ASASSN-21qj. Which choice most effectively uses relevant information from the notes to accomplish this goal?The star ASASSN-21qj was observed with increased infrared radiation, likely the result of a planetary collision, the debris of which then blocked light, resulting in repeated dimming of the star.eliminateAstronomer Matthew Kenworthy observed the star, ASASSN-21qj dimming repeatedly, which may have been caused by impact debris blocking light from the star.eliminateThe WISE telescope observed increased infrared radiation around ASASSN-21qj which scientists believe could be explained by a planetary collision. eliminateMatthew Kenworthy is an astronomer whose observation of a dimming star has led researchers to conclude that debris caused the star to dim.

Which of the following astronomical phenomenon were already observed by the ancientpeople even before the telescope was invented?A. Sunspot B. Craters of the Moon C. Solar eclipse D. Atmosphere of Mars

19)The Hubble Space Telescope (HST) is projected to maintain operation until at least 2030, but it has already revolutionized high-resolution imaging of solar-system bodies in visible and ultraviolet (UV) light wavelengths, notwithstanding that only about 6% of the bodies imaged by the HST are within the solar system. NASA researcher Cindy L. Young and colleagues assert that a new space telescope dedicated exclusively to solar-system observations would permit an extensive survey of minor solar-system bodies and long-term UV observation to discern how solar-system bodies change over time. Young and colleagues' recommendation therefore implies that the HST ______ Which choice most logically completes the text?IFRPRAEN-019will likely continue to be used primarily to observe objects outside the solar system.will no longer be used to observe solar system objects if the telescope recommended by Young and colleagues is deployed.can be modified to observe the features of solar system objects that are of interest to Young and colleagues.lacks the sensors to observe the wavelengths of light needed to discern how solar system bodies change over time.

The James Webb Space Telescope (JWST), launched in late 2021, represents a significant advancement in infrared astronomy, with capabilities far exceeding those of its predecessors. Its mission includes peering into the earliest galaxies formed after the Big Bang, studying the formation of stars and planetary systems, and examining the atmospheres of exoplanets for potential signs of life. Given the JWST's focus on deep space phenomena and its enhanced resolution and sensitivity, NASA scientist Emma B. Rossi and her team propose that future missions should prioritize the development of complementary technologies that enable detailed surface mapping of exoplanets and moons within our solar system. Rossi and her team’s suggestion thus implies that the JWST ______15Mark for ReviewABCWhich choice most logically completes the text?Awill primarily be utilized for observing distant astronomical phenomena rather than detailed studies of solar system objects.Blacks the capability to conduct surface mapping of solar system bodies at the level of detail envisioned by Rossi and her team.Ccould be repurposed for solar system exploration if future technological advancements allow for it.Dis the only telescope capable of identifying potential signs of life on exoplanets, making other observational tools unnecessary.

From 2009 to 2013 the Kepler space telescope __________ 150,000 stars in an effort to discover Earth-like planets orbiting those stars. Recent advances in technology have made the search for these exoplanets, planets outside our solar system, possible.
