It was generally assumed that the first discovered interstellar object would be an icy body, like a comet. In effect, icy objects are constantly tossed out of their host systems. They are also much more visible due to their apparent coma. However, ‘Oumuamua’s dry appeara...
They also observed that while the object acquired a slight push away from the sun (a “rocket effect” common in comets as sunlight vaporizes the ices they are made of), the push was stronger than could be accounted for. Finally, the object lacked a de...
Time is ripe for the first missions in theinterstellar space. The scientific goals include the study of theHeliopauseand of theinterstellar medium,astrometrywith a very long baseline, the study of thegravitational lensingeffect of the Sun and the encounter with someKuiper belt object. Such missions...
The study analyzed the composition of these spherules and found the isotope distribution was so unusual they must have an interstellar origin. While that sounds compelling, there are a few caveats. The first is that the trajectory of the 2014 meteor isn’t that precisely known. We know the ...

(2007) that it is most probably originates from unresolved populations of low-luminosity X-ray binary systems. However, the nature of the dominant class of accreting objects contributing to the diffuse emission in this energy band in different regions of the Galaxy remains unclear. In contrast ...
There has been a long-running speculation discussion among lore buffs around the origin of the Observatories. For myself, I largely look at it through an architectural lens. The Directorate had a very distinctive organic “grown” look to all of their things, including their stations. Veniel ...
of the Royal Astronomical Society. The new results from theAtacama Large Millimeter/Submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, and from the ROSINA instrument onboard Rosetta, show that phosphorus monoxide is a key piece in the origin-of...
In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object. But, in the nearly two years since that historic announcement, and despite subsequent observations backing it up, uncertainty abo...
