NASA Goddard: The Moon May Have Frost

A recent discovery of unusually bright areas near the Moon’s south pole suggests that there could be plenty of water on the surface of the moon. Scientists using data from NASA’s Lunar Reconnaissance Orbiter, or LRO, have identified bright areas in craters near the moon’s south pole that are cold enough to have frost present …

Hydrogen found in plumes on Saturn’s moon Enceladus

Science Magazine explains the importance of finding hydrogen in the plumes of Enceladus. It is a sign of ongoing reactions on the floor of a probable subsurface alien sea and such chemistry provides energy for microbial life on Earth.  

NASA: Exploring Ocean Worlds with Robots

The search for life beyond Earth needs robots. But to explore distant ocean worlds like Europa, we’ll need a new set of tools to drill through ice, reach faraway samples and cross difficult terrain. NASA’s Jet Propulsion Laboratory recently finished a series of prototypes that might make that exploration a little easier.  

PBS: Space Time | Life on Europa?

The Hubble Telescope found more evidence of vast plumes of water bursting through the icy surface of Jupiter’s moon Europa. What does this tell us about the potential for life on Europa? New findings have increased the likelihood that there is a vast ocean lying under the surface of Europa. Jupiter’s moon is emerging as …

NASA: Hubble Directly Images Possible Plumes on Europa

NASA’s Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images. This adds another piece of supporting evidence to the existence of water vapor plumes on Europa – Hubble also …

TED: What a planet needs to sustain life | Dave Brain

“Venus is too hot, Mars is too cold, and Earth is just right,” says planetary scientist Dave Brain. But why? In this pleasantly humorous talk, Brain explores the fascinating science behind what it takes for a planet to host life — and why humanity may just be in the right place at the right time …

Silicon Valley Astronomy Lectures: Innumerable Globes Like This One: The Search for Life Beyond the Solar System

Dr. Tori Hoehler (NASA Ames Research Ctr.) Our Galaxy probably hosts billions of planetary systems. But how many of those globes are like the Earth and how can we determine whether life has taken hold there, too? In this talk, Dr. Hoehler discusses the science of searching for life beyond our immediate neighborhood, and how …

NASA: Measuring Mars’ Atmospheric Loss

A Nov. 5 NASA science update highlighted data from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission that has determined the present rate at which Mars’ atmosphere is losing gas to space, via stripping by the solar wind. This loss of gas to space appears to have played a key role in the transition of …

NASA Jet Propulsion Laboratory: NASA to Sample Alien Ocean

NASA’s Cassini spacecraft will sample an extraterrestrial ocean on Wednesday, Oct. 28, when it flies directly through a plume of icy spray coming from Saturn’s moon Enceladus. The agency held a news teleconference to discuss plans for and anticipated science results from the historic flyby. The teleconference participants are: — Curt Niebur, Cassini program scientist …

Gresham College: A Cosmic Perspective: Four Centuries of Expanding Horizons

The ‘curious and ingenious’ men who met at Gresham College and founded the Royal Society were fascinated by the Sun and Planets; the ‘fixed stars’ were a distant mystery to them. Over succeeding centuries, cosmic horizons have expanded – largely thanks to ever more powerful instruments. So has our understanding – though each advance brings …

NASA: Water Flowing on Present-Day Mars

During a news conference at NASA headquarters, agency scientists and officials discussed new findings from the Mars Reconnaissance Orbiter (MRO) that provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the …

Harvard University: Sarah Rugheimer | Sniffing the Air of Alien Earths

Are we alone in the universe? We’ve found hundreds of planets orbiting distant stars, including several dozen in their star’s habitable zone. But do any of them host life? To find out, we’ll need to look for telltale molecules like oxygen or methane. The next generation of telescopes may answer this question when they take …

NASA: Water in the Universe

This panel discussion from NASA headquarters focuses on recent discoveries of water and organics in our solar system, the role our sun plays in water-loss in neighboring planets, and our search for habitable worlds among the stars.  

NASA Jet Propulsion Laboratory: Europa | Ocean World

Scientists believe there is an ocean hidden beneath the surface of Jupiter’s moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity’s most profound questions.  

SciShow: Cloudy With A Chance Of Aliens: How We Look for Extraterrestrial Life

What do astronomers look for when they study exoplanets for signs of alien life? Hank explains how space telescopes are already yielding tantalizing clues of what other worlds might hold — including water! — and how the next generation of technology will be able to reveal to us. SciShow discusses science news and history and …

NASA: Water found in the atmospheres of 5 alien planets

Scientists say they have found evidence of water on five planets outside our solar system; WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b.. They have been using the Hubble Space Telescope, to study these planets they call “hot Jupiters,” they are massive worlds that orbit close to their stars. Nasa writes in a press release that the presence …
