Answer 1

Answer:

On March nights, we were treated to the glorious spectacle of Hyakutake spreading across the sky. Astronomers from all over the Earth turned to look at the comet. They were well rewarded. The Hubble Space Telescope got the first-ever look from the earth at the icy nucleus that inside a comet. (It is just around 2 kilometers in size.) For the first time, a comet was seen giving off X-rays faint, but because Hyakutake passed only 15 lakh kilometers from the earth. They were caught by an X-ray telescope. Other astronomers have been busy looking the spectrum of the comet. This usually gives a lot of information about the compounds that are in the comet (Jantar Mantar, Sep-Oct ’95). Michael Mumma and Michael Di Santi found methane in the comet, forming almost 1% of the comet’s ice. Until now, methane has only been found in the planets (such as Saturn) and their moons (like Titan). Happy at their success, Mumma and DiSanti then looked even more carefully at the spectral then even more carefully at the spectral lines of the comet. They found the lines of ethane, a compound which has not been found in space before. Ethane is another 1% of the comet’s ice. They are looking at the lines again. Who knows, they might even find something like naphthalene

Answer 2

Explanation:

A small number of “ultra-emitters” of methane from oil and gas production contribute as much as 12 percent of emissions of the greenhouse gas to the atmosphere every year — and now scientists know where many of these sources are.

Analyses of satellite images from 2019 and 2020 reveal that a majority of the 1,800 biggest methane sources come from six major oil- and gas-producing countries: Turkmenistan led the pack, followed by Russia, the United States, Iran, Kazakhstan and Algeria.

Plugging those leaks would not only be a boon to the planet, but also could save those countries billions in U.S. dollars, climate scientist Thomas Lauvaux of the University of Paris-Saclay and colleagues report in the Feb. 4 Science.

Ultra-emitters are sources that spurt at least 25 metric tons of methane per hour into the atmosphere. These occasional massive bursts make up only a fraction — but a sizable one — of the methane shunted into Earth’s atmosphere annually.
