In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational.

Meet 'Oumuamua, the first observed interstellar visitor to our solar system. At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system. Comets, in particular, are known to speed up due to "outgassing," a process in which the sun heats the surface of the icy comet, releasing melted gas.
But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt. Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. Going forward, the researchers believe we should search for other interstellar objects in our sky.
I will be truly excited once we have conclusive evidence. Other mysteries in space have previously been thought of as signs of extraterrestrial life: a mysterious radio signal, repeating fast radio bursts and even a strangely flickering star, known as Tabby's Star. The mysterious radio signal was later determined to be coming from Earth, the repeating fast radio bursts are still being investigated, and new research suggests that Tabby's Star is flickering because of dust -- rather than being an alien megastructure.
Jackson published a paper in the Monthly Notices of the Royal Astronomical Society in March that suggests that 'Oumuamua came from a binary star system, or a system with two stars.

Jackson said the spectral data from 'Oumuamua looks like an asteroid or a comet, while that of a solar sail would look very different. The new paper proposes that the sail has been coated in interstellar dust, which obscures its true spectral signature. If it was then deployed again on entering the solar system it would be pristine. Even if it was left deployed the dust accumulation would be primarily on the leading side like bugs on a windshield. Even the spinning motion of a damaged solar sail would be far more strongly influenced by the radiation forces than seen, he explained.
I started to cook a celebratory curry. At some point I forgot that I had just been chopping chillies and went to the toilet without washing my hands first. This involved the transfer of chilli to what a medical professional would later describe as the remains of my genitals. I was urgently easing the affected area into a family-sized tub of natural yoghurt when my girlfriend and several of her colleagues walked in.
Better yet, when Shrek 2 was first released. Apparently not. Humanity is at its lowest, most embarrassing ebb.

Nasa's most stunning pictures of space Show all For 50 years, NASA has been "suiting up" for spacewalking. The spectacular cosmic pairing of the star Hen — more commonly known as WR — and the nebula M which surrounds it. Nasa's Hubble Space Telescope has unveiled in stunning detail a small section of the Veil Nebula - expanding remains of a massive star that exploded about 8, years ago.
It also took caviar, ready for the satellite's inhabitants to celebrate the holidays. Virts took this photograph of the Gulf of Mexico and U.
The aliens are coming. And they’ve caught us with our pants down
Gulf Coast at sunset. Nasa celebrated Black Friday by looking into space instead — sharing pictures of black holes. The Orion capsule jetted off into space before heading back a few hours later — having proved that it can be used, one day, to carry humans to Mars. The Gemini IV crew conducted scientific experiments, including photography of Earth's weather and terrain, for the remainder of their four-day mission following Ed White's historic spacewalk on June 3. This image of an area on the surface of Mars, approximately 1. This near-infrared color image shows a specular reflection, or sunglint, off of a hydrocarbon lake named Kivu Lacus on Saturn's moon Titan.
Although Mimas and Pandora, shown here, both orbit Saturn, they are very different moons. Pandora, "small" by moon standards 50 miles or 81 kilometers across is elongated and irregular in shape.
Mimas miles or kilometers across , a "medium-sized" moon, formed into a sphere due to self-gravity imposed by its higher mass. An X1. Regions of space such as this are where new stars are born from a mixture of elements and cosmic dust. Nasa's Mars Rover Spirit took the first picture from Spirit since problems with communications began a week earlier.
The image shows the robotic arm extended to the rock called Adirondack. Nasa astronaut Scott Kelly captured this photograph of the green lights of the aurora from the International Space Station. The Space Shuttle Challenger launches from Florida at dawn.
