Solar System’s First Interstellar Visitor Dazzles Scientists

Solar System’s First Interstellar Visitor Dazzles Scientists

“Astronomers recently scrambled to observe an intriguing asteroid that zipped through the solar system on a steep trajectory from interstellar space-the first confirmed object from another star. Now, new data reveal the interstellar interloper to be a rocky, cigar-shaped object with a somewhat reddish hue. The asteroid, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long …

Lava or Not, Exoplanet 55 Cancri e Likely to have Atmosphere

Lava or Not, Exoplanet 55 Cancri e Likely to have Atmosphere

“Twice as big as Earth, the super-Earth 55 Cancri e was thought to have lava flows on its surface. The planet is so close to its star, the same side of the planet always faces the star, such that the planet has permanent day and night sides. Based on a 2016 study using data from NASA’s Spitzer Space Telescope …

We may have found 20 habitable worlds hiding in plain sight

“There could be more habitable planets out there than we thought. An analysis of data from the Kepler space telescope has revealed 20 promising worlds that might be able to host life. The list of potential worlds includes several planets that orbit stars like our sun. Some take a relatively long time to complete a single orbit, with the longest …

Next Mars Rover Will Have 23 ‘Eyes’

Next Mars Rover Will Have 23 ‘Eyes’

“When NASA’s Mars Pathfinder touched down in 1997, it had five cameras: two on a mast that popped up from the lander, and three on NASA’s first rover, Sojourner. Since then, camera technology has taken a quantum leap. Photo sensors that were improved by the space program have become commercially ubiquitous. Cameras have shrunk in size, increased in …

NuSTAR Probes Black Hole Jet Mystery

NuSTAR Probes Black Hole Jet Mystery

“ Black holes are famous for being ravenous eaters, but they do not eat everything that falls toward them. A small portion of material gets shot back out in powerful jets of hot gas, called plasma, that can wreak havoc on their surroundings. Along the way, this plasma somehow gets energized enough to strongly radiate light, forming two bright columns along …

“Lighten Up” - Deep Space Communications via Faraway Photons

“Lighten Up” - Deep Space Communications via Faraway Photons

“A spacecraft destined to explore a unique asteroid will also test new communication hardware that uses lasers instead of radio waves. The Deep Space Optical Communications (DSOC) package aboard NASA’s Psyche mission utilizes photons — the fundamental particle of visible light — to transmit more data in a given amount of time. The DSOC goal is to increase spacecraft communications performance …

Orionid Meteor Shower

Orionid Meteor Shower

“The Orionid meteor shower is expected to peak before dawn on October 21, with up to 20 meteors visible an hour; however, many meteors may still be seen between October 20-22. In fact, outside of this peak period you may still be able to spot a few Orionids between October 2 through November 7. _As with observing any meteor shower …

NASA Missions Catch First Light from a Gravitational-Wave Event

NASA Missions Catch First Light from a Gravitational-Wave Event

“For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra. Shortly after 8:41 a.m. EDT on Aug. 17, NASA’s Fermi Gamma-ray Space Telescope picked up a pulse of high-energy light from …
