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” […]
Astronomers Find and Confirm 44 New Extrasolar Planets
An international team of astronomers has confirmed the existence of 44 new extrasolar planets. The planets were first spotted by the astronomers through data gathered from Campaign #10 of NASA’s Kepler K2 mission. According to NASA’s Kepler and K2 webpage, campaign #10 ran from July 6, 2016, to September 20, 2016. To verify their findings, […]
First Detection of Helium in an Exoplanet Atmosphere
Scientists say for the first several hundred thousand years or so after the Big Bang, there were virtually only two elements in the universe, hydrogen, and helium. A hydrogen atom is made of only one proton and one electron, and a helium atom has two each of protons, electrons, and neutrons. Hydrogen and then helium are […]
NASA Launches TESS the Exoplanet Hunter
The Transiting Exoplanet Survey Satellite, or TESS, will soon join NASA’s fleet of exoplanet-hunters that, so far, includes the Kepler, Hubble, and the Spitzer Space Telescopes. TESS was launched at 2251 UTC on April 18, 2018, from the Cape Canaveral Air Force Station in Florida. The space observatory is expected to survey about 85% of […]
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 […]
Lots of Water Detected in Exoplanet WASP 39b Atmosphere
Scientists, who studied a “hot Jupiter-like” exoplanet with NASA’s Hubble and Spitzer space telescopes, were able to detect signs of water in its atmosphere. And, they didn’t just find signs of a little water – but a lot of water, three times the amount of water on our solar system’s largest planet, Jupiter. The exoplanet they […]
First Extragalactic Planets Found
No doubt you’ve heard about extrasolar or exoplanets; planets that were discovered orbiting a star outside of our own solar system. Nearly 3,000 of these planets have been confirmed so far, with many more candidate planets waiting to be verified. However, these planets have all been discovered within our own Milky Way galaxy. An astrophysics […]
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, […]
Solar System Mimics Ours; The Big Empty; Closest Human Relative?
Nearby Planetary System Mimics our Solar System A group of scientists using NASA’s airborne Stratospheric Observatory for Infrared Astronomy or SOFIA recently completed a study that confirmed their previous findings of a young and nearby planetary system. The researchers found that the system surrounding the star Epsilon Eridani, which is about 10.5 light years away […]
Dark Matter Imaged; Shoe-String Theory; Metal in Mars Atmosphere
Dark Matter Filaments of Cosmic Web Imaged Two Canadian researchers say that they have constructed a composite image of dark matter filaments that make up what cosmologists call the cosmic web. Scientists have been finding evidence that our universe may be anything but random and that everything is actually organized and connected to each other […]
