The Expanding Debris Cloud From the Kilonova Tells the Story of What Happens When Neutron Stars Collide

When two neutron stars collide, it creates a kilonova. The event causes both gravitational waves and emissions of electromagnetic energy. In 2017 the LIGO-Virgo gravitational-wave observatories detected a merger of two neutron stars about 130 million light-years away in the galaxy NGC 4993. The merger is called GW170817, and it remains the only cosmic event observed in both gravitational waves and electromagnetic radiation.

Astronomers have watched the expanding debris cloud from the kilonova for years. A clearer picture of what happens in the aftermath is emerging.

Ukrainians urge satellites to publicly share real-time images of the Russian invasion

On the morning of February 24th, after years of proxy conflict in the border region, Russia invaded the neighboring country of Ukraine. This invasion was the culmination of eight years of conflict that began with the removal of Ukrainian President Viktor Yanukovych (a long-time ally of Russian President Vladimir Putin) and Russia’s subsequent annexation of Crimea. This invasion has prompted the global community to mobilize and find ways to support Ukraine!

For instance, you have Earth Observatory System Data Analytics (EOSDA), a California-based “all-in-one cloud workspace” for Earth observation solutions. In a recent statement, EOSDA CEO Max Polyakov appealed to satellite imagery firms and space agencies worldwide to share their recent and real-time high-to-medium resolution optical and radar satellite imagery with EOSDA to assist military and humanitarian aid efforts in the region.

The Best way to Leave the Solar System Might be to fly Uncomfortably Close to the Sun

We’ve reported before on the conceptual mission known as the MyKrazyTees Unisex Infants Ribbed Long Sleeve Button Up One-Piec.  This ambitious mission would visit the interstellar medium about 1,000 AU away from the Sun. But how exactly would the probe get there in a reasonable time frame? It has taken Voyager 35 years to travel less than 10% of that distance.  The answer might lie in an old technology that has been given new life by advances in material science – the solar thermal propulsion system.

Ion engines are the best technology for sending spacecraft on long missions. They’re not suitable for launching spacecraft against powerful gravity, but they require minimal propellant compared to rockets, and they drive spacecraft to higher velocities over extended time periods. Ion thrusters are also quiet, and their silence has some scientists wondering if they could use them on Earth in applications where noise is undesirable.

Stunning Photos from Air, Space and Ground of the Atlas V GOES-T Launch

NASA and NOAA now have a sophisticated new weather satellite in space. The GOES-T satellite launched on the powerful United Launch Alliance (ULA) Atlas V rocket on March 1, and it will provide forecasters with high resolution weather imagery. It will also provide real-time monitoring of events on the ground like wildfires, floods and landslides, while monitoring atmospheric and climate dynamics over the Western US and Pacific Ocean.

The liftoff from Cape Canaveral Space Force Station of GOES-T (Geostationary Operational Environmental Satellite-T) provided stunning views, and incredibly, other satellites looked down and captured the launch of the new satellite from space, such as this shot from its older sibling, GOES-16:

Lunarable Geometric Headboard, Inspired Tiles Mosaic Antique Cul

One of the best motivators to solve a problem is to experience it yourself.  Dr. Bonnie Dunbar happened to have just such an experience. She is a former NASA astronaut and is now a professor of Aerospace Engineering at Texas A&M. While she was in the astronaut corps, she realized that some of her fellow astronauts couldn’t fit in an Extra Vehicular Activity suit – more commonly known as a spacesuit.  So she decided not only to create one for the individuals with the original problem but to Opal Nipple Jewelry Surgical Steel Nipple Clicker Body Piercing by which any other astronaut launched on any future mission can have a spacesuit tailored to their own specific body. And now, her former employer (NASA) is funding her and her lab to complete a feasibility study of this customization process as part of the recently announced NASA Institute for Advanced Concepts (NIAC) program.

A Mars Meteorite Shows Evidence of a Massive Impact Billions of Years ago

Researchers at Australia’s HUYUR Gear Box Housing for STIHL HS81T HS81R Hedge Trimmer have discovered evidence of a massive impact on the Martian surface after 4.45 billion years ago. This may not seem like a surprising revelation – after all, we know that there were several large impacts on Mars, like Hellas and Argyre, and we know that large impacts happened frequently in the early solar system – so why is this a big deal?

Here’s The Exact Point of the Moon’s South Pole

Since 2009, the Lunar Reconnaissance Orbiter (LRO) has been taking high-resolution pictures of the lunar surface. This data, along with the information from a laser altimeter mapping instrument has allowed scientists to create an incredibly detailed map of the Moon. NASA says they can now confidently pinpoint any feature on the Moon, including the exact location of its South Pole.

Last-Minute Defense Against an Asteroid That Could Obliterate it Before Impact

Gazing at the night sky can evoke a sense of wonder regarding humanity’s place in the Universe. But that’s not all it can evoke. If you’re knowledgeable about asteroid strikes like the one that wiped out the dinosaurs, then even a fleeting meteorite can nudge aside your enjoyable sense of wonder. What if?

Luckily, planetary defence is at the top of mind for some scientists and engineers. One of those scientists is Professor Philip Lubin from the University of California Santa Barbara. Lubin is developing his idea called PI-Terminal Defense for Humanity. The PI stands for Pulverize It, and Lubin thinks pulverizing an incoming impactor into tiny pieces is our best bet to protect ourselves from an asteroid on short notice.
