Hubble Space Observation

[27] Scientists can determine what a distant star is made of by looking at ____.

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

The planet, which hasn't been officially named yet, was found by Brown and colleagues using the Samuel

Scientists found a new plant that has this star that’s so hot that they disbelieve there could be any molecules living on this planet named “Kelt-9b”. The founders go to the Ohio State University in Columbus, Ohio the team tells us how this planet is three times bigger than Jupiter, and the star that lives as its next door neighbor is nearly twice as hot as our own sun. The planet moves around the sun like star every one and a half earth days one side of the planet is locked into a face to face with the star which makes the face of Kelt-9b be around 7,820 degrees Fahrenheit. For a long time scientists have been focused on finding small planets by cool stars because technology today it’s easier to study atmospheres of planets potentially find

Scientists have discovered a new planet that they believe may be capable of housing life. LHS 1140 b, the planet in question, is six times heavier than Earth, yet only 1.5 times as large, suggesting that it is an extremely dense ball of metal and rock. LHS 1140 b is ten times closer to its sun than Earth, as well, making the orbit only 25 days. The sun LHS 1140 b orbits, LHS 1140, is an old, dim red dwarf star, 40 light-years from Earth in the constellation Cetus. Everything about it is rather ordinary; red dwarfs are the most common type of star, and the light that LHS 1140 produces is too dim to be spotted with the naked eye.

much a star wobbles or goes around the centre of gravity of the exoplanet and star, the violent wobbles must conclude that 51 Pegasi b is a Jupiter sized exoplanet. Hd209458 b is also a Jupiter sized exoplanet, which may have been determined using the calculation or the wobble method, having similar affects to its host stars light spectrum as 51 Pegasi b has on its host star. Astronomers are unsure whether the exoplanet named Kepler 22b is a larger Earth or more of a mini Neptune, as it is boarder line between a rocky planet and a gas dwarf.

Parenago 1802, a member of the ∼1 Myr Orion Nebula Cluster, is a double-lined, detached eclipsing binary in a 4.674 d orbit, with equal-mass components (M2/M1=0.985±0.029). Here we present extensive V IC JHKS light curves spanning ∼15 yr, as well as a Keck/HIRES optical spectrum. The light curves evince a third light source that is variable with a period of 0.73 d, and is also manifested in the high-resolution spectrum, strongly indicating the presence of a third star in the system, probably a rapidly rotating classical T Tauri star. We incorporate this third light into our radial velocity and light curve modeling of the eclipsing pair, measuring accurate masses (M1=0.391±0.032, M2=0.385±0.032 M⊙), radii (R1=1.73±0.02, R2=1.62±0.02 R⊙), and temperature ratio (Teff,1/Teff,2=1.0924±0.0017). Thus the radii of the eclipsing stars differ by 6.9±0.8%, the temperatures differ by 9.2±0.2%, and consequently the luminosities differ by 62±3%, despite having masses equal to within 3%. This could be indicative of an age difference of ∼ 3 × 105 yr between the two eclipsing stars, perhaps a vestige of the binary formation history. We find that the eclipsing pair is in an orbit that has not yet fully circularized,

Findings revealed that the system is located 39 light years from the solar system and is in the constellation of Aquarius. The system is formed of at least seven planets that orbit around a star that according to trappist.one is 12 times less massive than the Sun (“About Trappist-1 p.1”). Following findings made by the TRAPPIST, Spitzer space telescope, the Very Large Telescope, UKIRT, the Liverpool Telescope, and the William Herschel Telescope revealed new planets in the system and more facts about the composition of the planets. The discoveries made about the planets in the Trappist-1 system show surprising and promising aspects that might be promising evidence for a habitable

You are not able to see planets with a naked eye so Nasa uses telescopes to see in higher depth . There are different kind of telescopes that are used to look outside the Solar System some of the names are X-ray and gamma-ray telescopes and Kepler .The telescopes detect distant of planets by measuring the minute dimming of a star as an orbiting planet passes between it and the earth.Nasa has not been that useful of finding that many exoplanets because they are still trying to find out have much light they need to let in to make sure they can see the exoplanets. Nasa said that they will not stop looking until they find as many as they can.

NASA Confirms Planet Discovery Only 21 Light Year Away; Comments on Kepler 452b: 'So What Else Is New?'

An Orange giant, it is the 51st brightest star in our sky, a member of a multiple-star system with a confirmed planet. (5) The planet that was discovered orbiting Algieba is eight times the size of Jupiter. (2)

ike William Herschel, I share his interest in Astronomy, so it was easy for me to focus my research on Herschel’s discovery of Uranus, the seventh planet from the Sun, in 1781. There are two unique aspects to this discovery: first, this was the first planet to be discovered with the use of a telescope, and second, it was discovered by Herschel who began his career in Astronomy as an amateur.

The eighth, and final planet, in the solar system is Neptune. Neptune is in some ways a twin to Uranus, for example, it is slightly smaller at 49,528 km, is slightly warmer at -214 degrees Celsius, and has many of the same features that Uranus has. Neptune’s surface is also slightly darker than Uranus’ because there is more methane in the atmosphere above its clouds. (1) However, Neptune has more markings than Uranus. For example, one feature called the “Great Dark Spot”, much like Jupiter’s “Great Red Spot”, was seen by the Voyager 2 in August of 1989. The spot has disappeared, but more like it have popped up in its place. Also, to observe Neptune, it can be easily followed using binoculars, but it is too faint to view with the naked eye.

The first exoplanet found, Peg 51 b, challenged the then present theory of giant planet formation. Models of giant planet formation stated that Jupiter-like planets form at distances of 4-5 AU, AU being the distance from
