What may well be the most exciting astronomical discovery of the year has been making significant press in the first month of 2021. A team of astronomers led by Jacinta Delhaize, a postdoctoral fellow at the University of Cape Town’s Astronomy Department have used the world’s most sensitive radio telescope to discover two new giant radio galaxies at distances of roughly 2.6 and 5.8 billion light-years from Earth. …


A new, sophisticated framework for visualising scientific data

A Spiral Galaxy imaged with CARTA v1.4

How well professional Astronomers are able to visualise the data spewed out by powerful telescopes is the cornerstone to deepening our understanding of the distant Universe and discovering new phenomena taking place within it. When you think of the vast expanse that is the Cosmos, it is actually quite remarkable that instruments, over decades, have been able to image objects that existed millions sometimes billions of years ago. Last year’s image of the black-hole lurking at the centre of galaxy M87 left many in awe. …

Some History

Verizon Media is the two-year-old subsidiary of the Verizon Communications conglomerate responsible for developing online, digital media and advertising services. The subsidiary emerged in the wake of Verizon’s well-chronicled acquisition of two companies that played a massive role in ushering in a host of widely-used digital services for online communication and web-browsing during the dotcom boom of the mid-90s — AOL and Yahoo!

Until early 2019, AOL and Yahoo! formed part of a Verizon company division known as Oath Inc. which later went on to be christened with a new name — Verizon Media. Today, Verizon Media serves as the…


Subtle differences between Python methods you already know

Throughout undergrad, I would hear the phrase “there are several ways to skin a cat” repeated by lecturers during math, applied math and physics classes. As awry and violent as I found this Mark Twain phrase, it stuck with me (oddly enough) as a light reminder that there is always a multitude of probable routes one can take in achieving a goal. This helps me quite a lot when deciding on which methods to use in coding.

In my early days, all I knew was range() as a method for generating monotonically increasing (or decreasing) sequences in Python. Then I…
