An interstellar meteor could hit Earth and its effects are fascinating

A recent study by two Harvard researchers shows that five years ago, the cosmos had already dropped the first such distant visitor on our doorstep when a small meteorite near Papua New Guinea in the South Pacific fell to Earth. According to her research, this 1.5-foot-wide object was most likely from another solar system. Think about it: An object that …

Halo Drive: Black Holes to Accelerate the Interstellar Vehicle to LIGHT SPEED Science | news

Black holes are space-time regions with such strong gravitational effects that nothing – even light – can escape. Our understanding of black holes begins to grow after LIGO has recently detected gravitational waves – and provides the first direct evidence of the existence of black holes. And a Columbia University astrophysicist believes that black holes provide an unprecedented opportunity for …

NASA's Voyager 2 was interstellar the same day a sun probe touched the sun

WASHINGTON – let's call it a cosmic coincidence: two probes launched four decades apart, traveling in opposite directions – and used similar instruments to collect mileage data within hours. This scientific poetry took place on 5 November. With no orchestrated computations or trajectory maneuvers, the Voyager 2 probe on that day reached the interstellar space where the freshly launched Parker …

Why Voyager 2 is in interstellar space, but not outside the solar system

From Popular Mechanics Earlier this week, Voyager 2 was the second man-made object to reach interstellar space. Until it actually leaves our solar system, it is still a long way to go. Here is the reason. Five years ago, when the first Voyager became the first earth-built thing to become interstellar, five years ago, as he had gone beyond the …
