  • New Pluto Images Even More Perplexing

    Pluto has terrain like no other world, leaving scientists perplexed; Enceladus’ activity is also inexplicable for “geologic time”. More images of Pluto just came down from New Horizons on the 24th. Audible gasps come from the scientists, and from anyone … Continue reading

  • Watch solar tornado five times the diameter of Earth tear across Sun’s surface

    A solar tornado has been shown tearing across the surface of the sun for 40 hours. Temperatures in the tornado reached about 2.8 million degrees C. (or 5 million degrees F), Nasa said. CLICK HERE TO WATCH THE SOLAR TORNADO!  … Continue reading

  • Black holes are a passage to another universe, says Stephen Hawking

    Humans could escape from black holes, rather than getting stuck in them, according to a new theory proposed by Stephen Hawking. Unfortunate space travellers won’t be able to return to their own universe, according to Hawking. But they will be … Continue reading

  • Giant Galaxy Ring Shouldn’t Exist

    A team of astronomers from Hungary and the United States, led by Professor Lajos Balázs of Konkoly Observatory in Budapest, has announced the discovery of an enormous ring of galaxies. According to the Big Bang model, this ring should not … Continue reading

  • Astrobiology: The Joy of Being Wrong

    An astrobiologist looks forward to the day when everything he says is totally wrong. What makes a planet habitable? In a BBC News article, astrobiologist Christopher Watson (Queen’s University, Belfast) piles on the constraints: “Clouds are reflective and therefore will cool the planet, … Continue reading

  • Planets Defy Bottom-Up Assembly

    As much as they want to imagine planets forming from dust, secular astronomers run into insurmountable difficulties. Look at what’s implied in this headline by Rohini Giles on The Conversation: “‘Teenage’ Jupiter may hold the secret of how planets form.” What’s … Continue reading

  • Big Bang Antimatter Problem Deepens

    The most precise measurements ever show that particles and their antiparticles are perfect mirror images of each other. Protons and anti-protons are alike in every way; just don’t bring them together or they will annihilate each other. They differ only … Continue reading

  • Does a Distant Galaxy Show Star Formation?

    Some scientists refer to certain dust and debris clouds in galaxies as star “incubators” because they think stars form naturally within them. But since the formation of a star from a compacted cloud would take far too long to observe … Continue reading

  • Magnetic News

    Magnetism is an important force in astronomy, planetary science and life. Here are news items involving magnets and magnetic fields. These are offered for interested researchers. One should keep a distinction between observation and hypothesis, especially when dealing with theories … Continue reading

  • Ski Pluto: Glaciers Are Flowing

    Planetary scientists are dumbfounded by more evidence of youth at Pluto, both on the surface and in the atmosphere. Last Friday’s news conference contained more detailed images of Pluto. Alan Stern first shared a global portrait with twice the resolution … Continue reading

  • Pluto Is Young

    The New Horizons science team is stunned by surface features on Pluto and its large moon Charon that cannot be billions of years old. In the video, Deputy Project Scientist Cathy Olkin excitedly described the huge canyons and cliffs, the … Continue reading

  • Where Are the Earth’s Impact Craters?

    The number of impact craters on Earth is almost negligible compared to Mars and the moon. Can erosion explain this? Scientists have estimated that there must be about 340 undiscovered meteor craters on the Earth, Science Daily reports. Only 188 have been … Continue reading

  • Admit It: Mars Is Lifeless

    How much longer does the public have to be told that Mars “might” have life or space aliens “could” be found soon? A writer for New Scientist is concerned about the cost of protecting Mars from contamination. But the argument bears on … Continue reading

  • Discovery: Volcanoes on Venus

    The tortured surface of Venus appears to have been formed through recent geologic processes, and its rocks contain no record of deep time.1 What if Venus were young rather than 4.5 billion years old? It would explain quite a bit, including … Continue reading

  • Will Pluto Surprise Scientists?

    First-time encounters have a long history of shocking planetary scientists with unexpected features. It’s about time for Pluto. Since New Horizons was launched in 2006, Pluto went from planet to minor planet to plutoid to dwarf planet. The Plutonians surely don’t care … Continue reading

  • The seven-day cycle

    What is the origin of the names we use for the days of the week? It doesn’t take long to discover they are identified with seven pagan gods associated with the five major planets plus the sun and moon. This … Continue reading

  • Desperately Seeking Life Beyond Earth

    Earth life cannot be unique. How about you, Mars? Europa, anything? Enceladus? Comet 67P? Please break the silence! Comet 67P The latest evidence-starved speculation about life beyond Earth is that Rosetta’s lander Philae is sitting on a world sculpted by microbes (see PhysOrg). … Continue reading

  • Natural Light Shows Dazzle Scientists

    Here are some news stories from diverse fields of science, related only by the phenomenon of light. Independence Day is a time for explosions of light in the dark. Nature’s light explosions can be strictly physical, but the most interesting … Continue reading

  • To Discover Irreducibly Complex Mechanisms, Biologists Reverse Engineer a Worm

    My master’s degree research focused on paleomagnetism and I’ve always been fascinated by the earth’s magnetic field. So naturally I was interested in new research by biologists at the University of Texas, Austin, published in the journal eLife, “Magnetosensitive neurons mediate … Continue reading

  • Fire and Brimstone: Why Earth Isn’t Like Venus

    Both planets have abundant sulfur, but Earth life has a way of cycling it for good. The recent evidence for active volcanism on Venus (Science Magazine, Science Daily) has excited planetary scientists who long suspected it. Eight years ago, spikes in … Continue reading
