Best Evidence Yet for Midsized Black Holes Found by Hubble Because astronomers think they're missing an important link between the smallest and largest black holes, confirming that IMBHs exist would have powerful implications for the evolution of these light-gobbling beasts.
Sun in April, 2020 April 2nd, 2020, 12:50 p.m. local time. It has been a while since I looked at the Sun through a telescope. This mildly-warm Spring day with few clouds seemed like the perfect opportunity to see what the fireball in the sky was up to. This was a somewhat rush job, as technically I needed to get back to my job.
Astronomers Make It Rain, Search for Gin and Vampires Many of the world's premier professional telescopes are in drought-stricken areas, from the Canary Islands and Chile to Australia, which earlier this year was hit by devasting fires. Astronomers could alleviate these regions' dry spells by assigning Lund time on local telescopes - the more time, the better.
An Eclipse Globe for the 21st Century There's a saying that goes: "Once you've seen your first total solar eclipse, your first four words are 'When's the next one?'" Millions of skywatchers all across the U.S. got a chance to witness totality on August 21, 2017, and most of them were indeed seeing the Sun's corona for the first time.
How a Star Expands Well, everyone, look who's back! For those of you who are not signed up for my newsletter, I'm sorry I've been away forever-life happened. It's been a very rough three months.

The Nocturnal Magellan probably used this instrument to tell time at night, called the nocturnal. If you live in the northern hemisphere, you might notice that the Big Dipper and the northern constellations revolve around Polaris, the North Star. The nocturnal tells you what time it is based on a star's position in the sky.

My Argument for Agnosticism Let me start by saying, I do not believe in God. My faith and beliefs lie solely in science, theories and laws based on replicable and verifiable research. And yet it is this belief in science that makes me an agnostic. For those of you who don't know what agnosticism is, here's a brief explanation:.
Introducing a new Speaker Series - SkyNews The Royal Astronomical Society of Canada and SkyNews are teaming up to co-host a new Speaker Series online, bringing those in the know to your screen. From what went wrong on Apollo 13 to the Hubble Space Telescope's 30th anniversary, the Speaker Series is set to focus on important issues and hot topics in the skies.
"The Broken Hill Skull" - Does This 300,000-Year-Old Fossil Upend Human Evolution? The research also suggests that human evolution in Africa around 300,000 years ago was a much more complex process, with the co-existence of different human lineages.
Watch as the James Webb telescope unfolds its 18 gold-plated hex mirrors Engineers test James Webb Space Telescope's mirror by unfolding its segments.
Threes - "Omne Trium Perfectum" When I was growing up, I often heard people say "Three for a Welsh girl". It could refer to three good things or three bad things, and I never questioned why this should be so or why, as I thought at that time, it only applied to Welsh girls.
Venus and the Pleiades in April Venus is currently the brilliant evening star. Shared around world, in tonight’s sky Venus will begin to wander across the face of the lovely Pleiades star cluster. This digital sky map illus…

If you've been reading my emails lately, you know that Doctor Rex Parker, PhD, and I conducted a Keyholder training session on Sunday, March 8, 2020. We focused on the clubs' expanding Electronically Assisted Astronomy capabilities.
April Astronomy: In These Isolated, Scary Times, Take Solace by Going Outside and Looking at the Wonders of the Universe In the western sky at dusk, Venus in April attains its greatest brilliance of this year. Before dawn, the three bright outer planets-Mars, Jupiter and Saturn-are visible in the southeast before dawn. In the evening: Going eastward against the background stars of Taurus at a decreasing pace, Venus loses altitude late in the month.
Human urine could help astronauts build Moon bases — no joke European researchers have found that the second-most abundant component of urine - urea - can serve as an effective plasticizer that helps keep 3D-printed structures workable while still maintaining their strength and stability during hardening.
Strange Happenings in April The abundance of free time many of us have found ourselves with has in a way, created a strange new pressure. We should be making the most of our newfound leisure time, shouldn't we? But many experts caution against throwing ourselves into too many activities at once.
Venus on Approach and a Comet I snapped a few images of Venus "the evening star" approaching the Pleiades star cluster last night and I've provided an image of what those of you in the northern hemisphere might expect to see in binoculars. When two or more celestial objects have an apparent meeting or passing in the night sky, we call this a conjunction.
Why Have Parts of Mercury's Landscape "Deflated"? The team found that once enough of these volatiles escaped, the landscape deflated, creating irregular ground with drops of more than one kilometer. Their findings appear online March 16th in Scientific Reports.
"Warping Spacetime to Explore Uncharted Realms" - NASA Seeks Out Hidden Planets at Milky Way's Center NASA's WFIRST's infrared telescope will explore uncharted regions of the galaxy for exoplanets due to the different goals of previous missions. Kepler, for example, searched a modest-sized region of about 100 square degrees with 100,000 stars at typical distances of around a thousand light-years.
Video Chat From Outer Space With These Custom Wallpapers Since some services like Zoom allow you to create virtual backgrounds, I thought I might offer you the opportunity to take your home office to Mars, or the Moon, or other fun places in space. Here's a collection of images sized and cropped specifically for use as backgrounds for video.
How does NASA keep COVID-19 off the space station? Those early traditions carried over to the ISS, and they still help keep astronauts from getting sick in space today. "The ISS Program has always had requirements in place to address preventing any disease-causing agent from being transferred to the ISS and thus potentially to the flight crew," NASA ISS spokesperson Dan Huot tells Astronomy.
