Answer:
They measure the shift in a star's emission spectrum.
Explanation:
Exoplanets are planets found outside the solar system.
Planets orbiting far enough from stars to be resolved reflect very little starlight, so planets are detected through their thermal emission instead. These thermal emission is gotten by observing the shift in the stars emission spectrum.
Coronagraphs are also used to block light from the star which results to leaving the planet visible. Direct imaging of an Earth-like exoplanet requires extreme use of optothermal stability.
They can also be found by using space based telescopes.
25% chance because when you do a Punnett square for your genes you find that only 1 of 4 are tt and 2 are TT and one is Tt so the percentage for the plant to be short would be 25%
The narrative and goals for what has become America’s longest war have shifted in the past 16 years, and they may take a new turn Monday night, as President Donald Trump is expected to announce his policy approach for Afghanistan.The war started in October 2001 in the wake of the September 11th attacks, under then-President George W. Bush, and after Obama, Trump is now the second president to inherit -- and have to make a decision on how to handle -- the ongoing conflict.
When Bush first announced the military action on Oct. 7, 2001, he described “strikes against al Qaeda terrorist training camps and military installations of the Taliban regime in Afghanistan.”
