Most surprising to cometary scientists was the first discovery of X-ray emission from a comet, believed to have been caused by ionised solar wind particles interacting with neutral atoms in the coma of the comet.

Most notable would be solar cells, which are still prohibitively expensive for most markets due to the high cost per unit area of traditional bulk ( mono-or polycrystalline ) silicon manufacturing.

Most practical active solar heating systems have storage for a few hours to a day's worth of heat collected in insulated hot water tanks, but this can be extended to interseasonal thermal storage using underground thermal energy storage.

Most of the Genesis collectors continuously sampled all of the solar wind which the spacecraft encountered ( the ‘ bulk solar wind ’).

Most recently, research suggests that there may also be regional climate impacts due to the solar cycle.

Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity, and some use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, and hydroelectric.

Most of what we talk about today — hybrid, biodiesel, ethanol, solar photovoltaics, geothermal — I believe are irrelevant to the scale of the problem.

Most countries generate electricity in large centralized facilities, such as fossil fuel ( coal, gas powered ), nuclear, large solar power plants or hydropower plants.

Most notably, in the episode, Janet's bragging about herself doesn't appear to be empty bragging and she constantly raves about how " proof " is needed for all extraordinary claims, prompting her to force Arnold to collect " proof " from every planet in the solar system, so she can prove to the students in her class that she actually traveled to all the planets.

Most aliens are from different planets, who have a source of origin near the Solar System and in the Milky Way Galaxy, although, unlike the Marvel Universe, alien colonies are common within the solar system.

Most proposed designs for solar thermal rockets use hydrogen as their propellant due to its low molecular weight which gives excellent specific impulse of up to 1000 seconds ( 10 kN · s / kg ) using heat exchangers made of rhenium.

Most commonly, five such higher-order cycles in a modified vigesimal ( base-20 ) count were used, generating a linear progression of days to span a period of roughly 5125 solar years.

Most recently, the NTT helped detect a disc around a massive young star, solving the mystery of star formation in massive stars, and its observations were crucial to determine how asteroids are modified by solar wind.

Most coronagraphs are intended to view the corona of the Sun, but a new class of conceptually similar instruments ( called stellar coronagraphs to distinguish them from solar coronagraphs ) are being used to find extrasolar planets around nearby stars.

Most designs featured a cluster of modules at the lower end and a set of articulated solar arrays at the upper end.

Most tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity Other parameters that effect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.

Most self-service huts have solar panels, and therefore electricity, but no running water, so they are usually located very close to a river from which buckets may be filled.

Most collectors decide to focus their financial resources on a narrower, specialist interest.

Most models come out of the box looking new, because unweathered finishes are easier to produce and many collectors want models to look pristine.

Most national post offices produce stamps that would not be produced if there were no collectors, some to a far more prolific degree than others.

Most nations have a national collectors ' organization, such as the American Philatelic Society in the United States.

Most collectibles are man-made commercial items, but some private collectors collect natural objects such as birds ' eggs, butterflies, rocks, and seashells.

Most such rifles, known to collectors as " ex-Dragoons ", can be identified by their pre-1930 date stampings, but small numbers of Dragoon rifles were produced from 1930 to 1932 and after reworking became impossible to distinguish from purpose-built M1891 / 30s.

Most of the time, collectors who make model airports use die-cast airline models for their creation.

Most Commonwealth countries still issue crown-sized coins for sale to collectors.

Most Jingdezhen porcelain is valued by collectors of antique porcelain throughout the world.

Most collectors prefer to collect mint condition duck stamps.

Most collectors will always prefer an Uncirculated note, and these notes command substantial premiums over lower grades.

Most collectors of numerical cancellations ignore the stamp itself, which may appear upside-down or sideways in albums or stock cards.

Most of this hobby centers on those computers manufactured after 1960, though there are collectors who specialize in pre-1960 computers as well.

Most flat plate collectors have a life expectancy of over 25 years.

Most vacuum tube collectors in use in middle Europe use heat pipes for their core instead of passing liquid directly through them.

Most were later destroyed as surplus and the few surviving examples are extremely rare collectors ' items.

Most original longboxes were discarded upon purchase, and they have since become desirable amongst music collectors.

Most of the issues were printed in larger quantities than the residents of Cape Juby could ever possibly use, were sold to collectors, and are today still quite common, with minimal value.

Most were lost to private collectors.

Most collectors believe that the " Babysitter " version is rarer than the " Carbona " version.

Most Midwestern collectors were still collecting works by the Barbizon School in the 1870s and 1880s, but thanks to the Palmers, this would soon change.

Most of the unreleased cards, printing plates, and company archives were thrown away in the 1960s, although some were sold to collectors.
