Iron and Titanium Found in Atmosphere of Ultra-hot Exoplanet
The chemical makeup of Earth’s atmosphere is said to contain about 78% Nitrogen and 21% oxygen, with argon, carbon dioxide, and other gases making up the remaining 1%. But an international team of scientists says they have detected vapors of iron and titanium in the atmosphere of what is considered to be the hottest “ultra-hot” […]
Newly Discovered Exoplanet Resembles Planet Mercury
A newly found exoplanet called K2-229b is about 20% larger and 2.5 times more massive than Earth. But the international team of astronomers, who recently discovered it, say it’s more like a super-charged version of our solar-system’s innermost planet, Mercury. They describe the planet as hot, metallic, made of iron and nickel, circles an orange K-dwarf […]
Hot Monster Planet; No Fountain of Youth; Sunscreen Snow on Exoplanet
Hot Monster Planet Found Orbiting Small Star British astronomers say they discovered a “monster” planet orbiting a tiny star, but, according to planet formation theory, the planet should not even exist. The theory suggests a planet of its size could not be formed around such a small star. Located about 600 light years from Earth, […]
Einstein Proven Correct; Gravitational Waves Detected; Super Hot Planet
Einstein Theory Confirmed Again In his 1915 Theory of General Relativity, physicist Albert Einstein proposed that mass can bend space time. And he predicted that when a distant star’s light passed by a large object en route to the observer, the object’s gravity can bend and brighten the starlight like a magnifying lens. This effect, called […]
Scientists Measure A Mighty Wind Blowing on Exoplanet
A pair of British scientists have found that winds of over 2 kilometers per second are blowing around HD 189733b, an exoplanet located about 63 light years away from us. According to the researchers, the exoplanet’s 2 kps wind speed is about seven times the speed of sound and is 20 times more than the […]
Astronomers Observe Exoplanet Temperatures Swinging Wildly
For the first time ever, scientists in the United Kingdom detected temperature fluctuations on a super-Earth exoplanet – 55 Cancri e, the so-called “diamond planet.” Using NASA’s Spitzer Space Telescope to study the rocky exoplanet’s thermal radiation over a two-year period, researchers led by the University of Cambridge found that the temperature on the side […]
