Researchers from MIT and collaborating institutions have uncovered exceptionally rare traces of “proto Earth,” the ancient precursor to our planet that existed about 4.5 billion years ago. This primitive world took shape before a massive collision forever changed its chemistry and gave rise to the Earth we inhabit today. TheContinue Reading
This new NASA/ESA Hubble Space Telescope Picture of the Week features a galaxy that’s hard to categorize. The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (The Crab). NGC 2775 sports a smooth, featureless center that is devoid of gas, resembling anContinue Reading
NASA’s Perseverance Rover spent three years exploring the floor of Jezero Crater, located just north of the Martian equator. This close-up look at what had previously been seen only from orbit revealed evidence of chemical reactions that shaped the planet billions of years ago. SETI Institute Senior Research Scientist JaniceContinue Reading
NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan. Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan’s lakes and seas are not filled with water. Instead, they contain liquidContinue Reading
In 2009, NASA’s Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. i> X-rays from Chandra have been combined with radio data obtained by the Australian Telescope Compact Array to reveal new structures. At the center of this image isContinue Reading
A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO2) in regions where Earth-like planets may one day form. The discovery, made using the James Webb Space Telescope (JWST), challenges long-standing assumptionsContinue Reading
The solar atmosphere, or corona, is far hotter than the Sun’s surface, a paradox that has puzzled scientists for decades. Furthermore, the constant outflow of plasma and magnetic fields from the Sun, known as the solar wind, is accelerated to incredible speeds. Turbulent dissipation – the process by which mechanicalContinue Reading
This post is cowritten with Renyu Chen and Dev Tagare from Robinhood. Robinhood has been a pioneer and disruptor in the once staid world of online brokerages. Founded in 2013, the company transformed an industry better known for gatekeeping into an open platform accessible to all. Robinhood pioneered commission-free trading,Continue Reading
Research from NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the Red Planet was ever capable of supporting life. Lead author Dr. Ben Tutolo, PhD, an associate professor with the Department of Earth, Energy and Environment inContinue Reading
A new study by planetary scientists at Brown University and the University of Bern in Switzerland casts doubt on one of the most tantalizing clues that water might be flowing on present-day Mars. For years, scientists have spied strange streaks running down Martian cliffsides and crater walls. Some have interpretedContinue Reading
