Space and astronomy news
Ready for the next great comet? First, the bad news. there is not (as of yet), a good naked eye comet in the cards, for 2020. The good news is… there is a fine binocular comet currently well-placed for northern hemisphere viewers: Comet T2 PanSTARRS.

A team of scientists in Canada have found a Fast Radio Burst (FRB) that repeats every 16 days. This is in stark contrast to other FRBs, which are more sporadic. Some of those sporadic FRBs occur in clusters, and repeat irregularly, but FRBs with a regular, repeatable occurrence are rare.

In 1802, German astronomer Heinrich Olbers observed what he thought was a planet within the Main Asteroid Belt. In time, astronomers would come to name this body Pallas, an alternate name for the Greek warrior goddess Athena. The subsequent discovery of many more asteroids in the Main Belt would lead to Pallas being reclassified as a large asteroid, the third-largest in the Belt after Ceres and Vesta.
For centuries, astronomers have sought to get a better look at Pallas to learn more about its size, shape, and composition. As of the turn of the century, astronomers had come to conclude that it was an oblate spheroid (an elongated sphere). Thanks to a new study by an international team, the first detailed images of Pallas have finally been taken, which reveal that its shape is more akin to a “golf ball” – i.e. heavily dimpled.

This week we are airing Fraser’s interview with Dr. Cole Miller, Professor of Astronomy at the University of Maryland, College Park. Dr. Miller led one of two separate teams that analyzed Neutron star Interior Composition Explorer (NICER) data – specifically that for pulsar called J0030+0451 (J0030) in the constellation Pisces – and were able to map the surface features of a pulsar for the first time.

The CHEOPS spacecraft is taking the first tentative steps in its mission. Back on January 29th, the spacecraft opened the cover on its lens. Now, we have the first images from CHEOPS.

This summer, between mid-July and early August, the Mars 2020 rover will launch, reaching Mars by February of 2021. Once it touched down in the Jezero Crater, it will carry on in the footsteps of its predecessor – the Curiosity rover. This will include searching for evidence of Mars’ past habitability and the possible existence of life (past and present), as well as a sample-return mission.
To accomplish these tasks, the Mars 2020 rover will be relying on an advanced suite of instruments. One of these is the SuperCam, which includes a camera, a laser, and spectrometers and is mounted to the rover’s mast (or “head”). Once operational, this instrument will be used to study the chemistry and mineralogy of Martian rocks and (with any luck) find evidence of fossilized microbial life on Mars.

Picture the space around Earth filled with tens of thousands of communications satellites. That scenario is slowly coming into being, and it has astronomers concerned. Now a group of astronomers have written a paper outlining their detailed concerns, and how all of these satellites could have a severe, negative impact on ground-based astronomy.

In May of 2019, SpaceX launched the first batch of satellites that will make up its Starlink constellation, thus delivering on Musk’s promise to provide broadband internet access to the whole world. Since then, the company has conducted several launches of upgraded satellites with the intent of creating a constellation of 1,584 by 2024 and 2,200 by 2027.
According to the latest statements made by Gwynne Shotwell, SpaceX’s President and Chief Operations Officer (COO), the company is considering spinning off Starlink and making it a publicly-traded company in the coming years. The announcement was made on Thursday, Feb. 6th, at a private investor event hosted by JPMorgan Chase & Co. in Miami.

In the coming years, a number of will be sent to space for the purpose of answering some of the enduring questions about the cosmos. One of the most pressing is the effect that solar activity and “space weather” events have on planet Earth. By being able to better-predict these, scientists will be able to create better early-warning systems that could prevent damage to Earth’s electrical infrastructure.
This is the purpose of the Solar Orbiter (SolO), an ESA-led mission with strong participation by NASA that launched this morning (Monday, Feb. 10th) from Cape Canaveral, Florida. This is the first “medium-class” mission implemented as part of the ESA’s Cosmic Vision 2015-25 program and will spend the next five years investigating the Sun’s uncharted polar regions to learn more about how the Sun works.
