Astronomers Detect Unexpected Activity in Largest Oort Cloud Comet

Astronomers have made an astonishing discovery about comet C 2014 UN271, the largest comet ever detected in the Oort Cloud. Despite being over a billion miles from the Sun, the comet is venting carbon monoxide gas, a phenomenon that was not expected at such a great distance. This comet, also known a... [More info]

Fascinating: ESA is now preparing the Comet Interceptor mission

The spacecraft will be launched in 2029 into a parking orbit, lying in wait for a suitable target – a pristine comet from the Oort Cloud, or, unlikely but highly appealing, an interstellar object.

Tohle je fasicnující - naprostou náhodou bylo díky vizualizaci reálných dat zjištěno, že Oortův oblak má ve skutečnosti tvar spirály (něco jako minigalaxie kolem Sluneční soustavy!)

An accidental discovery: astronomers find a spiral structure in the Oort cloud by chance after data from a simulation were visualized in preparation of a new space show at the Hayden Planetarium

Beyond excited to announce that our demo approaches at FTL speed!

It's coming from the Oort Cloud, and it arrives on June 30!

If my simple mathematical model holds, a comet in the Oort cloud who runs a 1.2 million year word-of-mouth campaign against the inevitable incursion of the star Gliese 710 will need to personally convince 42 comets if they want to get 5% of the cloud’s 20 trillion space rocks to sign their petition.

A Spiral Structure in the Inner Oort Cloud

fed.brid.gy/r/https://www.univ

<p>We typically think of the Oort cloud as scattered ice balls floating far from the Sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of them a weird way and create a long-period comet, which might briefly delight us lowly humans by providing something interesting in the sky to look at. But what the Oort cloud actually looks like and how it is affected by forces greater than just our solar system has remained somewhat of a mystery. A new paper from researchers at the Southwest Research Institute and the American Museum of Natural History tries to shine a light on what this invisible part of the solar system looks like &#8211; at least the part that is only 1,000 to 10,000 times farther away from the Sun as Earth is.</p> <span id="more-170976"></span> <p>That part called the &#8220;inner&#8221; Oort cloud is considered slightly more populated than the &#8220;outer&#8221; Oort cloud, which ranges from 10,000 AU to 100,000 AU. Overall, potentially trillions of icy bodies are thought to be floating deep in space, though we only ever see the ones that show up in the inner solar system as long-period comets. </p> <p>Estimating the cloud&#8217;s structure requires more than understanding the planet&#8217;s gravitational forces. While they still have an impact, there is a larger player in the orbital mechanics of these icy rocks—the galaxy itself.</p> <p>There&#8217;s a concept known as the &#8220;Galactic tid

Mucho se habla por estos días de las hazañas de las I y II las cuales salieron ya de la y están cruzando la (Nube de Oort) de la cual, saldrán dentro de 2.000 años, quizá cuando la humanidad ya no sea la misma ó esté extinta.
Es una hazaña dramática y la gente de este mundo no es consciente de lo que pasa "allá" fuera. Me da terror...a ti no?.

The vastness of Space, the Oort cloud and Voyager🧪

“Voyager 1, the fastest and farthest of the interplanetary space probes currently leaving the Solar System, will reach the Oort cloud in about 300 years and would take about 30,000 years to pass through it.”

Source: en.wikipedia.org/wiki/Oort_clo (Citations removed for clarity.)

Illustration of earth and our solar system compared to the Oort Cloud. Astronaut Chris Hadfield writes, "The size boggles my mind - that tiny thing in the middle is our solar system, surrounded by a huge Oort Cloud of dust, ice and rock. All held together by our Sun’s gravity."
