SPACE MOG: DR MAGGIE LIEU

Welcome to my channel! I'm Dr Maggie Lieu and I make youtube videos about space & astronomy. The curvature of the Universe is an important number for scientists in cosmology. This week I want to talk about the shape of the Universe and how it can determine our ultimate fate.

When stars die, they usually turn into white dwarves, neutron stars or black holes. But the lowest mass black hole is much larger than the heaviest neutron star, this mass gap has been boggling astronomers for years. So let's discuss! Special thanks to Dr Christopher Berry for helping me out on some of this week’s topic. For more info on mass gaps, be sure to check out Christophers blog, http://cplberry.com he’s also on twitter @cplberry.

Everyone has wanted to be an astronaut at one point in their lives. We've wanted to go to the moon or to Mars, or maybe even the next nearest star, Alpha Centuri. But this is thinking too small.... we need to aim higher. We should try to get out of our solar system! and I have just the plan. In this week's video I will be talking about how we can use ultrafast outflows from black holes and tidal disruption events to surf out of our galaxy. Special thanks to my amazing colleague Gabriele Matzeu who is an expert on UFOs for helping me out on this episode! Media credits: Alpha centuri: Bardon, NASA/CXC/UColorado/Ayres et al.

Apollo 11 landed on the moon on July 20th 1969. Neil Armstrong, Buzz Aldrin and Michael Collins, made history and inspired humanity. But 50 years later, humans have not been on the moon for the last 47 years. Why is this so? In this video I talk about the 1969 landings and what the prospects we have of doing it again photo/video credits: NASA/ESA/ROSCOSMOS/CNSA/CAST/Apollo archives

In this week's video, during my visit to Bern in Switzerland we talk about Einstein's life and in particular Special relativity, which Bern played a major role.

Hello from Ovronnaz, Switzerland! In preparation for this weeks total solar eclipse in Chile, this week I talk about the different types of solar eclipse, and why this is a particularly important one for the anniversary of 100 years of gravitational lensing! Furthermore, turn of events is what made Einstein who he is today. The total solar eclipse will be occurring on 2nd July. Check out ESA's CESAR page for more info on where you can observe and how to do so more safely. They will also have a live stream set up: http://cesar.esa.int/index.php?Section=Total_Solar_Eclipse_2019_plans&ChangeLang=es If you enjoyed the video, please help me by liking, sharing and subscribing!

Almost everyone at one point has dreamt about being an astronaut! But what does it take to make it? This week I talk about the requirements of being an astronaut in each of the national space agencies and how likely you really are to make it. If you like this video, please help me by sharing with your family and friends! Also I'm on all the social media outlets: facebook: Maggie Lieu twitter: space_mog instagram: space_mog Also check out my friend Andgies blog for more tips on how to be an astronaut: https://quokkaspace.wordpress.com/how-to-become-an-astronaut/

In this video I talk about the upcoming e-ROSITA mission on board of Spekr-RG due to launch Friday 21st June 2019. How X-ray detectors work, what they are good for looking at and how this mission will tear the skies apart.

ESA is the European Space Agency, composed of 22 Member States. Its mission is to develop space missions and to carry them out. The objective of these top-class programmes is to learn more about Earth, its near-spatial environment, our Solar System and the Universe. Our missions also help to conceive state-of-the-art technologies and satellite services, as well as promoting European industry. So that space discoveries benefit the whole of humankind, ESA works in cooperation with other space organisations beyond Europe. ESA also wants to share the knowledge of space and its everyday applications with everyone and invite you to share in the conversation. That’s why ESA initiated the My Space Dream contest: to hear the dreams and expectations of European space programmes so we can work on them every day. The videos will help to shape ESA for the space19+ ministerial meeting. This is my entry for the contest. Make sure you get yours in too at: https://www.myspacedream.com for a chance to train as an esa astronaut for the day!

In this week's video, I want to apologise for missing soapbox science Brighton by talking about dark matter. What is it? Why is it important? What do we know about it so far?

Big data is the next biggest challenge for astronomers and we are absolutely not prepared for it. We saw how the event horizon telescope generated a tiny image of the 1st ever super massive black hole, but in the near future, Euclid will be generating images of 1/3 of the entire sky - and they have to download it all the way from outer space! LSST will be imaging the entire sky every 3 nights and SKA will be generating more data than 10x the global internet does! Its scary times, so let's talk about it!

Blue Origin unveiled this week a lunar lander that they have been working on for the past 3 years. They call it Blue Moon but who is Blue Origin? and why is what they are doing so cool? Find out in this video Credits: blue origin, esa
