    On April 13, 2029, a 1,110-foot-wide asteroid known as 99942 Apophis will speed past our planet at an estimated distance of around 19,000 miles, potentially coming closer to the surface than some orbiting spacecraft. Despite being a decade away, this future close encounter is causing quite a stir within the asteroid research community. So much so that it is the focus of a session Tuesday at the 2019 Planetary Defense Conference in College Park, Maryland, during which scientists will discuss everything from potential observation strategies to hypothetical missions that could explore the object itself. On the day of the close...

    Asteroids have been hitting the Earth for nearly 1 billion years, but the atmosphere has largely shielded the planet from some catastrophic events. However, some space rocks make their way through — including the one that wiped out the dinosaurs. But a new study notes that, over the past 290 million years, asteroids have been impacting the Earth at triple the rate they were previously and scientists aren't sure why. After looking at 1 billion years' worth of asteroid impacts on both the Earth and Moon, researchers found that dinosaurs' fate was perhaps an inevitability.

    On January 3rd, 2019, Earth reached the point in its orbit where it's at its closest approach to the Sun: perihelion. Every object orbiting a single mass (like our Sun) makes an ellipse, containing a point of closest approach that's unique to that particular orbit, known as periapsis. For the past 4.5 billion years, Earth has orbited the Sun in an ellipse, just like all the other planets orbiting their stars in all the other mature solar systems throughout the galaxy and Universe. But there's something you may not expect or appreciate that nevertheless occurs: Earth's orbital path doesn't remain...

    DART's target Didymos was chosen based on very different criteria. It's a binary asteroid, which means DART can slam into the smaller object of the pair. But scientists can gather robust data about the bodies and their locations from Earth, which will help them track where to target the car-size spacecraft as well as how much the collision knocked the object off course.

    UNION GAP, WA - During a press conference on Thursday the Yakima Valley Office of Emergency Management (YVOEM) gave an update on the Rattlesnake Ridge landslide. They also mentioned new work that is set to begin next week near the landslide. YVOEM says the movement of the landslide has been decreasing since April. "The most recent surveys indicate that the fastest moving point is about .85 feet per week and the slowest moving point is .20 feet per week," said Horace Ward, Senior Emergency Planner at YVOEM. Ward says next week new equipment is set to be installed, "There is...
  • Huge magnetic tail discovered behind Mars

    10/22/2017 10:43:53 AM PDT · by BenLurkin · 15 replies
    Discovered by the Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft, the unusual phenomenon is thought to have been caused by the effects of the solar winds and could help to shine more light on how the Martian atmosphere escaped in to space. "We found that Mars' magnetic tail, or magnetotail, is unique in the Solar System," said NASA scientist Gina DiBraccio. "It's not like the magnetotail found at Venus, a planet with no magnetic field of its own, nor is it like Earth's, which is surrounded by its own internally generated magnetic field." "Instead, it is a hybrid between...

    Posted on November 9, 2018November 9, 2018 by Evan Gough Not all the Earth’s Water Came From Comets We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way.Hydrogen is the most abundant element in the universe, and it’s at the center of the question surrounding Earth’s water. This new study was co-led by Peter Buseck, Regents’ Professor in the School of...

    In further study of the Book of Isaiah today, reading in Chapter 40:21-26 (NIV), The Lord proclaims, "Do you not know? Have you not heard? Has it not been told you from the beginning? Have you not understood since the earth was founded? He sits enthroned above the circle of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in. He brings princes to naught and reduces the rulers of this world to nothing. No sooner are they planted, no sooner are they sown,...

    SpaceX founder and CEO Elon Musk is a big "Hitchhiker's Guide" fan, as Starman's Roadster shows. The car's entertainment display was programmed to read "Don't Panic!" — the phrase that adorns the cover of the eponymous electronic guidebook in Adams' beloved series. Musk has said that he launched the Roadster and Starman because the duo is a lot more fun than the typical inert-mass dummy payload... Launching a satellite or other valuable spacecraft wasn't an option, given the risks inherent in maiden flights. The Roadster and Starman will come within a few hundred thousand kilometers of our planet in 2091,...

    Moore’s Law: Life is Older than Earth Itself — “A Process that Began Billions of Years Before the Formation of Our Solar System” Posted on Sep 24, 2018  As life has evolved, its complexity has increased exponentially, just like Moore’s law which states that the number of transistors on an integrated circuit doubles approximately every two years. The regression suggests that if life takes 10 billion years to evolve to the level of complexity associated with homo sapiens, then we may be among the first, if not the first, intelligent civilization in the Milky Way, negating Drakes Equation.Our Solar...

  • Asteroid miners could use Earth’s atmosphere to catch space rocks

    Science ^ | 8/29/18 | Joshua Rapp Learn
    Forget deflecting asteroids from hitting Earth—some engineers are drawing up a strategy to steer asteroids toward us, so our atmosphere can act as a giant catching mitt for resource-rich space rocks. What might sound like a crazy idea is actually quite business savvy, according to Minghu Tan, a Ph.D. student at the University of Glasgow in the United Kingdom who co-authored the new study. That’s because such near-Earth asteroids can host supplies, such as water and precious metals, that could support future human missions to space. But other scientists are skeptical that the concept will ever get off the ground....

    (snip) --- A team of scientists made an enormous discovery when they recently uncovered a "quadrillion" tons of diamonds buried more than 100 miles below Earth's surface, according to a new study. Researchers from the Massachusetts Institute of Technology (MIT), Harvard, the Carnegie Institution of Washington and several other universities used seismic devices to measure the speed of sound waves traveling through the Earth's crust. "Sound waves move at various speeds through the Earth, depending on the temperature, density, and composition of the rocks through which they travel," MIT explained in a news release. "Scientists have used this relationship between...
  • Days on Earth Are Getting Longer, Thanks to the Moon

    Days on Earth are getting longer as the moon slowly moves farther away from us, new research shows.  The moon is about 4.5 billion years old and resides some 239,000 miles (385,000 kilometers) away from Earth, on average. However, due to tidal forces between our planet and the moon, the natural satellite slowly spirals away from Earth at a rate of about 1.5 inches (3.82 centimeters) per year, causing our planet to rotate more slowly around its axis.  Using a new statistical method called astrochronology, astronomers peered into Earth's deep geologic past and reconstructed the planet's history. This work revealed...

    Over the course of the past 200 million years, our planet has experienced four major geological periods (the Triassic, Jurassic and Cretaceous and Cenozoic) and one major ice age (the Pliocene-Quaternary glaciation), all of which had a drastic impact on plant and animal life, as well as effecting the course of species evolution. For decades, geologists have also understood that these changes are due in part to gradual shifts in the Earth’s orbit, which are caused by Venus and Jupiter, and repeat regularly every 405,000 years. But it was not until recently that a team of geologists and Earth scientists...

It is a common experience to look east onto the plains and on the horizon be able to clearly discern the curve of the earth. For those who have never had this experience, it can be quite an epiphany. Right there before your eyes you can actually see the curve of the globe of this wonderful place we call home.

    Some might say it’s paranoid to think about an asteroid hitting Earth and wiping us out. But the history of life on Earth shows at least 5 major extinctions. And at least one of them, about 65 million years ago, was caused by an asteroid. Preparing for an asteroid strike, or rather preparing to prevent one, is rational thinking at its finest. Especially now that we can see all the Near Earth Asteroids (NEAs) out there. The chances of any single asteroid striking Earth may be small, but collectively, with over 15,000 NEAs catalogued by NASA, it may be only...

    A flurry of earthquakes has hit Earth's Pacific plate over the past week, renewing fears a massive tremor is on the way after four disasters jolted the region in January. Quakes have hit near Japan, Guam and Taiwan around the planet's so-called 'Ring of Fire', a horseshoe-shaped zone that is a hotbed for tectonic and volcanic activity. Some have suggested the frequency and proximity of the tremors are signs of a bigger earthquake to come. Experts have claimed events around the Ring of Fire are rarely linked and that in most cases adjacent disasters are a coincidence.
