Hubble Captures Smoking Gun of a Newborn Star

Hubble Captures Smoking Gun of a Newborn Star

In this image, the NASA/ESA Hubble Space Telescope has captured the smoking gun of a newborn star, the Herbig–Haro objects numbered 7 to 11 (HH 7–11). These five objects, visible in blue in the top center of the image, lie within NGC 1333, a reflection nebula full of gas and dust found about a thousand light-years away from Earth.

Land Heavier Payloads on Mars. Aim for the Ground and Then Pull up at the Last Moment

Land Heavier Payloads on Mars. Aim for the Ground and Then Pull up at the Last Moment

In the coming decades, a number of missions are planned for Mars, which include proposals to send astronauts there for the first time. This presents numerous logistical and technical challenges, ranging from the sheer distance to the need for increased protection against radiation. At the same time, there is also the difficulty of landing on the Red Planet, or what is referred to as the “Mars Curse“.

Farewell, Opportunity: rover dies, but its hugely successful Mars mission is helping us design the next one

 Farewell, Opportunity: rover dies, but its hugely successful Mars mission is helping us design the next one

NASA’s Opportunity rover on Mars has been officially pronounced dead. Its amazingly successful mission lasted nearly 15 years, well beyond its initial three-month goal. Opportunity provided the first proof that water once existed on Mars and shaped its surface, a crucial piece of knowledge informing both current and future missions.

InSight has Placed its Heat Probe on the Martian Surface. The Next Step is to Jackhammer Down 5 Meters and Hope it Doesn’t Encounter a Large Rock

InSight has Placed its Heat Probe on the Martian Surface. The Next Step is to Jackhammer Down 5 Meters and Hope it Doesn’t Encounter a Large Rock

NASA’s InSight lander has finally placed its heat probe on the surface of Mars. The Heat Flow and Physical Properties Package (HP3) was deployed on February 12th, about one meter away from SEIS, the landers seismometer. Soon it’ll start hammering its way into the Martian soil.

NASA's Record-Setting Opportunity Rover Mission on Mars Comes to End

NASA's Record-Setting Opportunity Rover Mission on Mars Comes to End

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet. 

Thanks to Gaia, We Now Know Exactly When We’ll be Colliding with Andromeda

Thanks to Gaia, We Now Know Exactly When We’ll be Colliding with Andromeda

Astronomers have known for some time that the Milky Way and the Andromeda galaxies will collide on some future date. The best guess for that rendezvous has been about 3.75 billion years from now. But now a new study based on Data Release 2 from the ESA’s Gaia mission is bringing some clarity to this future collision.

We’ve discovered the world’s largest drum – and it’s in space

 We’ve discovered the world’s largest drum – and it’s in space

Universities in the US have long wrangled over who owns the world’s largest drum. Unsubstantiated claims to the title have included the “Purdue Big Bass Drum” and “Big Bertha”, which interestingly was named after the German World War I cannon and ended up becoming radioactive during the Manhattan Project

NASA’s Van Allen Probes Begin Final Phase of Exploration in Earth's Radiation Belts

NASA’s Van Allen Probes Begin Final Phase of Exploration in Earth's Radiation Belts

Two tough, resilient, NASA spacecraft have been orbiting Earth for the past six and a half years, flying repeatedly through a hazardous zone of charged particles around our planet called the Van Allen radiation belts. The twin Van Allen Probes, launched in August 2012, have confirmed scientific theories and revealed new structures and processes at work in these dynamic regions. Now, they're starting a new and final phase in their exploration.

Here’s a Clever idea. Build Moon Bases in Craters and then Fill them in with Lunar Regolith

Here’s a Clever idea. Build Moon Bases in Craters and then Fill them in with Lunar Regolith

In the coming decades, multiple space agencies are planning to send astronauts to the lunar surface. More than that, between the European Space Agency (ESA), the China National Space Administration (CNSA) and Roscomos, there are multiple plans to construct permanent outposts on the Moon. Perhaps the best-known of these is the ESA’s plan to build an International Lunar Village,

A Star’s Outburst is Releasing Organic Molecules Trapped in the ice Around it

According to widely-accepted theories, the Solar System formed roughly 4.6 billion years ago from a massive cloud of dust and gas (aka. Nebular Theory). This process began when the nebula experienced a gravitational collapse in the center that became our Sun. The remaining dust and gas formed a protoplanetary disk that (over time) accreted to form the planets.

How Big Would a Generation Ship Need to be to Keep a Crew of 500 Alive for the Journey to Another Star?

How Big Would a Generation Ship Need to be to Keep a Crew of 500 Alive for the Journey to Another Star?

There’s no two-ways about it, the Universe is an extremely big place! And thanks to the limitations placed upon us by Special Relativity, traveling to even the closest star systems could take millennia. As we addressed in a previous article, the estimated travel time to the nearest star system (Alpha Centauri) could take anywhere from 19,000 to 81,000 years using conventional methods.

Why the Future of Solar Power Is from Space

Why the Future of Solar Power Is from Space

Over seven decades ago in 1941, Isaac Asimov wrote a short story, “Reason” (PDF), in which energy captured from the sun was transmitted via microwave beams to nearby planets from a space station. Flash forward to today, scientists are looking to make that very science fiction dream a reality for Earth.

ESA is Planning a Mission to the Smallest Spacerock Ever Visited: the Moon of an Asteroid

For some small minority of humans, Death By Asteroid is a desirable fate. The idea probably satisfies their wonky Doomsday thinking. But for the rest of us, going out the same way the dinosaurs did would just be embarrassing. Thankfully, the ESA’s Hera mission will visit the smallest spacerock ever, and will help us avoid going the way of the dinosaurs.
